 *
 * @description
 * Determines if two objects or two values are equivalent. Supports value types, arrays and
 * objects.
 *
 * Two objects or values are considered equivalent if at least one of the following is true:
 *
 * * Both objects or values pass `===` comparison.
 * * Both objects or values are of the same type and all of their properties pass `===` comparison.
 *
 * During a property comparision, properties of `function` type and properties with names
 * that begin with `$` are ignored.
 *
 * Note: This function is used to augment the Object type in Angular expressions. See
 * {@link angular.Array} for more information about Angular arrays.
 *
 * @param {*} o1 Object or value to compare.
 * @param {*} o2 Object or value to compare.
 * @returns {boolean} True if arguments are equal.
 *
 * @example

/**
 * @workInProgress
 * @ngdoc function
 * @name angular.compile
 * @function
 *
 * @description
 * Compiles a piece of HTML string or DOM into a template and produces a template function, which
 * can then be used to link {@link angular.scope scope} and the template together.
 *
 * The compilation is a process of walking the DOM tree and trying to match DOM elements to
 * {@link angular.markup markup}, {@link angular.attrMarkup attrMarkup},
 * {@link angular.widget widgets}, and {@link angular.directive directives}. For each match it
 * executes corresponding markup, attrMarkup, widget or directive template function and collects the
 * instance functions into a single template function which is then returned.
 *
 * The template function can then be used once to produce the view or as it is the case with
 * {@link angular.widget.@ng:repeat repeater} many-times, in which case each call results in a view
 * that is a DOM clone of the original template.
 *
   <pre>
    // compile the entire window.document and give me the scope bound to this template.
    var rootScope = angular.compile(window.document)();

    // compile a piece of html
    var rootScope2 = angular.compile('<div ng:click="clicked = true">click me</div>')();

    // compile a piece of html and retain reference to both the dom and scope
    var template = angular.element('<div ng:click="clicked = true">click me</div>'),
        scope = angular.compile(template)();
    // at this point template was transformed into a view
   </pre>
 *
 *
 * @param {string|DOMElement} element Element or HTML to compile into a template function.
 * @returns {function([scope][, cloneAttachFn])} a template function which is used to bind template
 * (a DOM element/tree) to a scope. Where:
 *
 *  * `scope` - A {@link angular.scope Scope} to bind to. If none specified, then a new
 *               root scope is created.
 *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
 *               `template` and call the `cloneAttachFn` function allowing the caller to attach the
 *               cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
 *               called as: <br/> `cloneAttachFn(clonedElement, scope)` where:
 *
 *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
 *      * `scope` - is the current scope with which the linking function is working with.
 *
 * Calling the template function returns the scope to which the element is bound to. It is either
 * the same scope as the one passed into the template function, or if none were provided it's the
 * newly create scope.
 *
 * If you need access to the bound view, there are two ways to do it:
 *
 * - If you are not asking the linking function to clone the template, create the DOM element(s)
 *   before you send them to the compiler and keep this reference around.
 *   <pre>
 *     var view = angular.element('<p>{{total}}</p>'),
 *         scope = angular.compile(view)();
 *   </pre>
 *
 * - if on the other hand, you need the element to be cloned, the view reference from the original
 *   example would not point to the clone, but rather to the original template that was cloned. In
 *   this case, you can access the clone via the cloneAttachFn:
 *   <pre>
 *     var original = angular.element('<p>{{total}}</p>'),
 *         scope = someParentScope.$new(),
 *         clone;
 *
 *     angular.compile(original)(scope, function(clonedElement, scope) {
 *       clone = clonedElement;
 *       //attach the clone to DOM document at the right place
 *     });
 *
 *     //now we have reference to the cloned DOM via `clone`
 *   </pre>
 *
 *
 * Compiler Methods For Widgets and Directives:
 *
 * The following methods are available for use when you write your own widgets, directives,
 * and markup.  (Recall that the compile function's this is a reference to the compiler.)
 *
 *  `compile(element)` - returns linker -
 *  Invoke a new instance of the compiler to compile a DOM element and return a linker function.
 *  You can apply the linker function to the original element or a clone of the original element.

/**
 * DESIGN NOTES
 *
 * The design decisions behind the scope ware heavily favored for speed and memory consumption.
 *
 * The typical use of scope is to watch the expressions, which most of the time return the same
 * value as last time so we optimize the operation.
 *
 * Closures construction is expensive from speed as well as memory:
 *   - no closures, instead ups prototypical inheritance for API
 *   - Internal state needs to be stored on scope directly, which means that private state is
 *     exposed as $$____ properties
 *
 * Loop operations are optimized by using while(count--) { ... }
 *   - this means that in order to keep the same order of execution as addition we have to add
 *     items to the array at the begging (shift) instead of at the end (push)
 *
 * Child scopes are created and removed often
 *   - Using array would be slow since inserts in meddle are expensive so we use linked list
 *
 * There are few watches then a lot of observers. This is why you don't want the observer to be
 * implemented in the same way as watch. Watch requires return of initialization function which
 * are expensive to construct.

 * @ngdoc function

 *
 * @description
 * A root scope can be created by calling {@link angular.scope angular.scope()}. Child scopes
 * are created using the {@link angular.scope.$new $new()} method.
 * (Most scopes are created automatically when compiled HTML template is executed.)
 *
 * Here is a simple scope snippet to show how you can interact with the scope.
 * <pre>
       var scope = angular.scope();
       scope.salutation = 'Hello';
       scope.name = 'World';

       expect(scope.greeting).toEqual(undefined);

       scope.$digest(); // fire all  the watches
       expect(scope.greeting).toEqual('Hello Misko!');
 * </pre>
 *
 * # Inheritance
 * A scope can inherit from a parent scope, as in this example:
 * <pre>
     var parent = angular.scope();
     var child = parent.$new();

     parent.salutation = "Hello";
     child.name = "World";

 * # Dependency Injection
 * See {@link guide/dev_guide.di dependency injection}.
 *
 *
 * @param {Object.<string, function()>=} providers Map of service factory which need to be provided
 *     for the current scope. Defaults to {@link angular.service}.
 * @param {Object.<string, *>=} instanceCache Provides pre-instantiated services which should
 *     append/override services provided by `providers`. This is handy when unit-testing and having

   * @function
   *
   * @description
   * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
   *
   * - The `watchExpression` is called on every call to {@link angular.scope.$digest $digest()} and
   *   should return the value which will be watched. (Since {@link angular.scope.$digest $digest()}
   *   reruns when it detects changes the `watchExpression` can execute multiple times per
   *   {@link angular.scope.$digest $digest()} and should be idempotent.)
   * - The `listener` is called only when the value from the current `watchExpression` and the
   *   previous call to `watchExpression' are not equal. The inequality is determined according to
   *   {@link angular.equals} function. To save the value of the object for later comparison
   *   {@link angular.copy} function is used. It also means that watching complex options will
   *   have adverse memory and performance implications.
   * - The watch `listener` may change the model, which may trigger other `listener`s to fire. This
   *   is achieved by rerunning the watchers until no changes are detected. The rerun iteration
   *   limit is 100 to prevent infinity loop deadlock.
   *
   *
   * If you want to be notified whenever {@link angular.scope.$digest $digest} is called,
   * you can register an `watchExpression` function with no `listener`. (Since `watchExpression`,
   * can execute multiple times per {@link angular.scope.$digest $digest} cycle when a change is
   * detected, be prepared for multiple calls to your listener.)

/**
 * @ngdoc function
 * @name angular.element
 * @function
 *
 * @description
 * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
 * `angular.element` can be either an alias for [jQuery](http://api.jquery.com/jQuery/) function, if
 * jQuery is available, or a function that wraps the element or string in Angular's jQuery lite
 * implementation (commonly referred to as jqLite).
 *
 * Real jQuery always takes precedence over jqLite, provided it was loaded before `DOMContentLoaded`
 * event fired.
 *
 * jqLite is a tiny, API-compatible subset of jQuery that allows
 * Angular to manipulate the DOM. jqLite implements only the most commonly needed functionality
 * within a very small footprint, so only a subset of the jQuery API - methods, arguments and
 * invocation styles - are supported.
 *
 * Note: All element references in Angular are always wrapped with jQuery or jqLite; they are never
 * raw DOM references.
 *
 * ## Angular's jQuery lite provides the following methods:
 *
 * - [addClass()](http://api.jquery.com/addClass/)
 * - [after()](http://api.jquery.com/after/)
 * - [append()](http://api.jquery.com/append/)
 * - [attr()](http://api.jquery.com/attr/)
 * - [bind()](http://api.jquery.com/bind/)
 * - [children()](http://api.jquery.com/children/)
 * - [clone()](http://api.jquery.com/clone/)
 * - [css()](http://api.jquery.com/css/)
 * - [data()](http://api.jquery.com/data/)
 * - [hasClass()](http://api.jquery.com/hasClass/)
 * - [parent()](http://api.jquery.com/parent/)
 * - [remove()](http://api.jquery.com/remove/)
 * - [removeAttr()](http://api.jquery.com/removeAttr/)
 * - [removeClass()](http://api.jquery.com/removeClass/)
 * - [removeData()](http://api.jquery.com/removeData/)
 * - [replaceWith()](http://api.jquery.com/replaceWith/)
 * - [text()](http://api.jquery.com/text/)
 * - [trigger()](http://api.jquery.com/trigger/)
 * - [eq()](http://api.jquery.com/eq/)
 *
 * ## In addtion to the above, Angular privides an additional method to both jQuery and jQuery lite:
 *
 * - `scope()` - retrieves the current Angular scope of the element.
 *
 * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
 * @returns {Object} jQuery object.

  /**
   * @ngdoc function
   * @name angular.Array.filter
   * @function
   *
   * @description
   * Selects a subset of items from `array` and returns it as a new array.
   *
   * Note: This function is used to augment the `Array` type in Angular expressions. See
   * {@link angular.Array} for more information about Angular arrays.
   *
   * @param {Array} array The source array.
   * @param {string|Object|function()} expression The predicate to be used for selecting items from
   *   `array`.
   *
   *   Can be one of:
   *
   *   - `string`: Predicate that results in a substring match using the value of `expression`
   *     string. All strings or objects with string properties in `array` that contain this string
   *     will be returned. The predicate can be negated by prefixing the string with `!`.
   *
   *   - `Object`: A pattern object can be used to filter specific properties on objects contained
   *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
   *     which have property `name` containing "M" and property `phone` containing "1". A special
   *     property name `$` can be used (as in `{$:"text"}`) to accept a match against any
   *     property of the object. That's equivalent to the simple substring match with a `string`
   *     as described above.
   *
   *   - `function`: A predicate function can be used to write arbitrary filters. The function is
   *     called for each element of `array`. The final result is an array of those elements that
   *     the predicate returned true for.

 * @workInProgress
 * @ngdoc filter
 * @name angular.filter.html
 * @function
 *
 * @description
 *   Prevents the input from getting escaped by angular. By default the input is sanitized and
 *   inserted into the DOM as is.
 *
 *   The input is sanitized by parsing the html into tokens. All safe tokens (from a whitelist) are
 *   then serialized back to properly escaped html string. This means that no unsafe input can make
 *   it into the returned string, however, since our parser is more strict than a typical browser
 *   parser, it's possible that some obscure input, which would be recognized as valid HTML by a
 *   browser, won't make it through the sanitizer.
 *
 *   If you hate your users, you may call the filter with optional 'unsafe' argument, which bypasses
 *   the html sanitizer, but makes your application vulnerable to XSS and other attacks. Using this
 *   option is strongly discouraged and should be used only if you absolutely trust the input being
 *   filtered and you can't get the content through the sanitizer.
 *
 * @param {string} html Html input.
 * @param {string=} option If 'unsafe' then do not sanitize the HTML input.
 * @returns {string} Sanitized or raw html.

   * Use asynchronous validator if the validation can not be computed

   *
   * @param {string} value value to validate

   *         of the input.
   * @param {function(data)=} [update=noop] function to call when state of the
   *    validator changes
   *
   * @paramDescription
   * The `validate` function (specified by you) is called as
   * `validate(inputToValidate, validationDone)`:
   *
   *    * `inputToValidate`: value of the input box.
   *    * `validationDone`: `function(error, data){...}`
   *       * `error`: error text to display if validation fails
   *       * `data`: data object to pass to update function
   *
   * The `update` function is optionally specified by you and is
   * called by <angular/> on input change. Since the
   * asynchronous validator caches the results, the update
   * function can be called without a call to `validate`
   * function. The function is called as `update(data)`:
   *
   *    * `data`: data object as passed from validate function
   *
   * @css ng-input-indicator-wait, ng-validation-error
   *
   * @example

/**
 * @workInProgress
 * @ngdoc service
 * @name angular.service.$resource
 * @requires $xhr.cache
 *
 * @description
 * A factory which creates a resource object that lets you interact with
 * [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources.
 *
 * The returned resource object has action methods which provide high-level behaviors without
 * the need to interact with the low level {@link angular.service.$xhr $xhr} service or
 * raw XMLHttpRequest.
 *
 * @param {string} url A parameterized URL template with parameters prefixed by `:` as in
 *   `/user/:username`.
 *
 * @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in
 *   `actions` methods.
 *
 *   Each key value in the parameter object is first bound to url template if present and then any
 *   excess keys are appended to the url search query after the `?`.
 *
 *   Given a template `/path/:verb` and parameter `{verb:'greet', salutation:'Hello'}` results in
 *   URL `/path/greet?salutation=Hello`.
 *
 *   If the parameter value is prefixed with `@` then the value of that parameter is extracted from
 *   the data object (useful for non-GET operations).
 *
 * @param {Object.<Object>=} actions Hash with declaration of custom action that should extend the
 *   default set of resource actions. The declaration should be created in the following format:
 *
 *       {action1: {method:?, params:?, isArray:?, verifyCache:?},
 *        action2: {method:?, params:?, isArray:?, verifyCache:?},
 *        ...}
 *
 *   Where:
 *
 *   - `action` – {string} – The name of action. This name becomes the name of the method on your
 *     resource object.
 *   - `method` – {string} – HTTP request method. Valid methods are: `GET`, `POST`, `PUT`, `DELETE`,
 *     and `JSON` (also known as JSONP).
 *   - `params` – {object=} – Optional set of pre-bound parameters for this action.
 *   - isArray – {boolean=} – If true then the returned object for this action is an array, see
 *     `returns` section.
 *   - verifyCache – {boolean=} – If true then whenever cache hit occurs, the object is returned and
 *     an async request will be made to the server and the resources as well as the cache will be
 *     updated when the response is received.
 *
 * @returns {Object} A resource "class" object with methods for the default set of resource actions
 *   optionally extended with custom `actions`. The default set contains these actions:
 *
 *       { 'get':    {method:'GET'},
 *         'save':   {method:'POST'},
 *         'query':  {method:'GET', isArray:true},
 *         'remove': {method:'DELETE'},
 *         'delete': {method:'DELETE'} };
 *
 *   Calling these methods invoke an {@link angular.service.$xhr} with the specified http method,
 *   destination and parameters. When the data is returned from the server then the object is an
 *   instance of the resource class `save`, `remove` and `delete` actions are available on it as
 *   methods with the `$` prefix. This allows you to easily perform CRUD operations (create, read,
 *   update, delete) on server-side data like this:
 *   <pre>
        var User = $resource('/user/:userId', {userId:'@id'});
        var user = User.get({userId:123}, function(){
          user.abc = true;
          user.$save();
        });
     </pre>
 *
 *   It is important to realize that invoking a $resource object method immediately returns an
 *   empty reference (object or array depending on `isArray`). Once the data is returned from the
 *   server the existing reference is populated with the actual data. This is a useful trick since
 *   usually the resource is assigned to a model which is then rendered by the view. Having an empty
 *   object results in no rendering, once the data arrives from the server then the object is
 *   populated with the data and the view automatically re-renders itself showing the new data. This
 *   means that in most case one never has to write a callback function for the action methods.
 *
 *   The action methods on the class object or instance object can be invoked with the following
 *   parameters:
 *
 *   - HTTP GET "class" actions: `Resource.action([parameters], [success], [error])`
 *   - non-GET "class" actions: `Resource.action(postData, [parameters], [success], [error])`
 *   - non-GET instance actions:  `instance.$action([parameters], [success], [error])`
 *
 *
 * @example
 *
 * # Credit card resource
 *
 * <pre>
     // Define CreditCard class
     var CreditCard = $resource('/user/:userId/card/:cardId',
      {userId:123, cardId:'@id'}, {
       charge: {method:'POST', params:{charge:true}}
      });

     // We can retrieve a collection from the server
     var cards = CreditCard.query();
     // GET: /user/123/card
     // server returns: [ {id:456, number:'1234', name:'Smith'} ];

     var card = cards[0];
     // each item is an instance of CreditCard
     expect(card instanceof CreditCard).toEqual(true);
     card.name = "J. Smith";
     // non GET methods are mapped onto the instances
     card.$save();
     // POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}
     // server returns: {id:456, number:'1234', name: 'J. Smith'};

     // our custom method is mapped as well.
     card.$charge({amount:9.99});
     // POST: /user/123/card/456?amount=9.99&charge=true {id:456, number:'1234', name:'J. Smith'}
     // server returns: {id:456, number:'1234', name: 'J. Smith'};

     // we can create an instance as well

     expect(newCard.id).toEqual(789);
 * </pre>
 *
 * The object returned from this function execution is a resource "class" which has "static" method
 * for each action in the definition.
 *
 * Calling these methods invoke `$xhr` on the `url` template with the given `method` and `params`.
 * When the data is returned from the server then the object is an instance of the resource type and
 * all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD
 * operations (create, read, update, delete) on server-side data.

   <pre>
     var User = $resource('/user/:userId', {userId:'@id'});
     var user = User.get({userId:123}, function(){
       user.abc = true;
       user.$save();
     });
   </pre>
 *
 *     It's worth noting that the success callback for `get`, `query` and other method gets passed
 *     in the response that came from the server, so one could rewrite the above example as:
 *
   <pre>
     var User = $resource('/user/:userId', {userId:'@id'});
     User.get({userId:123}, function(u){
       u.abc = true;
       u.$save();
     });
   </pre>

 *
 * @property {Object} current Reference to the current route definition.
 * @property {Array.<Object>} routes Array of all configured routes.
 *
 * @description
 * Watches `$location.hashPath` and tries to map the hash to an existing route
 * definition. It is used for deep-linking URLs to controllers and views (HTML partials).
 *
 * The `$route` service is typically used in conjunction with {@link angular.widget.ng:view ng:view}
 * widget and the {@link angular.service.$routeParams $routeParams} service.
 *
 * @example
   This example shows how changing the URL hash causes the <tt>$route</tt>
   to match a route against the URL, and the <tt>[[ng:include]]</tt> pulls in the partial.
   Try changing the URL in the input box to see changes.

/**
 * @workInProgress
 * @ngdoc service
 * @name angular.service.$xhr
 * @function
 * @requires $browser $xhr delegates all XHR requests to the `$browser.xhr()`. A mock version
 *                    of the $browser exists which allows setting expectations on XHR requests
 *                    in your tests
 * @requires $xhr.error $xhr delegates all non `2xx` response code to this service.
 * @requires $log $xhr delegates all exceptions to `$log.error()`.
 *
 * @description
 * Generates an XHR request. The $xhr service delegates all requests to
 * {@link angular.service.$browser $browser.xhr()} and adds error handling and security features.
 * While $xhr service provides nicer api than raw XmlHttpRequest, it is still considered a lower
 * level api in angular. For a higher level abstraction that utilizes `$xhr`, please check out the
 * {@link angular.service.$resource $resource} service.
 *
 * # Error handling
 * If no `error callback` is specified, XHR response with response code other then `2xx` will be
 * delegated to {@link angular.service.$xhr.error $xhr.error}. The `$xhr.error` can intercept the
 * request and process it in application specific way, or resume normal execution by calling the
 * request `success` method.
 *
 * # HTTP Headers
 * The $xhr service will automatically add certain http headers to all requests. These defaults can
 * be fully configured by accessing the `$xhr.defaults.headers` configuration object, which
 * currently contains this default configuration:
 *
 * - `$xhr.defaults.headers.common` (headers that are common for all requests):
 *   - `Accept: application/json, text/plain, *\/*`
 *   - `X-Requested-With: XMLHttpRequest`
 * - `$xhr.defaults.headers.post` (header defaults for HTTP POST requests):
 *   - `Content-Type: application/x-www-form-urlencoded`
 *
 * To add or overwrite these defaults, simple add or remove a property from this configuration
 * object. To add headers for an HTTP method other than POST, simple create a new object with name
 * equal to the lowercased http method name, e.g. `$xhr.defaults.headers.get['My-Header']='value'`.
 *
 *
 * # Security Considerations
 * When designing web applications your design needs to consider security threats from
 * {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
 * JSON Vulnerability} and {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF}.
 * Both server and the client must cooperate in order to eliminate these threats. Angular comes
 * pre-configured with strategies that address these issues, but for this to work backend server
 * cooperation is required.
 *
 * ## JSON Vulnerability Protection
 * A {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
 * JSON Vulnerability} allows third party web-site to turn your JSON resource URL into
 * {@link http://en.wikipedia.org/wiki/JSON#JSONP JSONP} request under some conditions. To
 * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
 * Angular will automatically strip the prefix before processing it as JSON.
 *
 * For example if your server needs to return:
 * <pre>
 * ['one','two']
 * </pre>
 *
 * which is vulnerable to attack, your server can return:
 * <pre>
 * )]}',
 * ['one','two']
 * </pre>
 *
 * angular will strip the prefix, before processing the JSON.
 *
 *
 * ## Cross Site Request Forgery (XSRF) Protection
 * {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which an
 * unauthorized site can gain your user's private data. Angular provides following mechanism to
 * counter XSRF. When performing XHR requests, the $xhr service reads a token from a cookie
 * called `XSRF-TOKEN` and sets it as the HTTP header `X-XSRF-TOKEN`. Since only JavaScript that
 * runs on your domain could read the cookie, your server can be assured that the XHR came from
 * JavaScript running on your domain.
 *
 * To take advantage of this, your server needs to set a token in a JavaScript readable session
 * cookie called `XSRF-TOKEN` on first HTTP GET request. On subsequent non-GET requests the server
 * can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure that only
 * JavaScript running on your domain could have read the token. The token must be unique for each
 * user and must be verifiable by the server (to prevent the JavaScript making up its own tokens).
 * We recommend that the token is a digest of your site's authentication cookie with
 * {@link http://en.wikipedia.org/wiki/Rainbow_table salt for added security}.
 *
 * @param {string} method HTTP method to use. Valid values are: `GET`, `POST`, `PUT`, `DELETE`, and
 *   `JSON`. `JSON` is a special case which causes a
 *   [JSONP](http://en.wikipedia.org/wiki/JSON#JSONP) cross domain request using script tag
 *   insertion.
 * @param {string} url Relative or absolute URL specifying the destination of the request.  For
 *   `JSON` requests, `url` should include `JSON_CALLBACK` string to be replaced with a name of an
 *   angular generated callback function.
 * @param {(string|Object)=} post Request content as either a string or an object to be stringified
 *   as JSON before sent to the server.
 * @param {function(number, (string|Object))} success A function to be called when the response is
 *   received. The success function will be called with:
 *
 *   - {number} code [HTTP status code](http://en.wikipedia.org/wiki/List_of_HTTP_status_codes) of
 *     the response. This will currently always be 200, since all non-200 responses are routed to
 *     {@link angular.service.$xhr.error} service (or custom error callback).
 *   - {string|Object} response Response object as string or an Object if the response was in JSON
 *     format.
 * @param {function(number, (string|Object))} error A function to be called if the response code is
 *   not 2xx.. Accepts the same arguments as success, above.

 *
 * Angular directives create custom attributes for DOM elements. A directive can modify the

 * DOM; instead, use {@link angular.widget widgets} to add DOM elements.
 *
 * Following is the list of built-in Angular directives:
 *
 * * {@link angular.directive.ng:autobind ng:autobind} - An Angular bootstrap parameter that can
 * act as a directive.
 * * {@link angular.directive.ng:bind ng:bind} - Creates a data-binding between an HTML text value
 * and a data model.
 * * {@link angular.directive.ng:bind-attr ng:bind-attr} - Creates a data-binding in a way similar
 * to `ng:bind`, but uses JSON key / value pairs to do so.
 * * {@link angular.directive.ng:bind-template ng:bind-template} - Replaces the text value of an
 * element with a specified template.
 * * {@link angular.directive.ng:change ng:change} - Executes an expression when the value of an
 * input widget changes.
 * * {@link angular.directive.ng:class ng:class} - Conditionally set a CSS class on an element.
 * * {@link angular.directive.ng:class-even ng:class-even} - Like `ng:class`, but works in
 * conjunction with {@link angular.widget.@ng:repeat} to affect even rows in a collection.
 * * {@link angular.directive.ng:class-odd ng:class-odd} - Like `ng:class`, but works with {@link
 * angular.widget.@ng:repeat}  to affect odd rows.
 * * {@link angular.directive.ng:click ng:click} - Executes custom behavior when an element is
 * clicked.
 * * {@link angular.directive.ng:controller ng:controller} - Creates a scope object linked to the
 * DOM element and assigns behavior to the scope.
 * * {@link angular.directive.ng:hide ng:hide} - Conditionally hides a portion of HTML.
 * * {@link angular.directive.ng:href ng:href} - Places an href in the Angular namespace.
 * * {@link angular.directive.ng:init} - Initialization tasks run before a template is executed.
 * * {@link angular.directive.ng:show ng:show} - Conditionally displays a portion of HTML.
 * * {@link angular.directive.ng:src ng:src} - Places a `src` attribute into the Angular namespace.
 * * {@link angular.directive.ng:style ng:style} - Conditionally set CSS styles on an element.
 * * {@link angular.directive.ng:submit} - Binds Angular expressions to `onSubmit` events.

 * @description
 * The `ng:controller` directive assigns behavior to a scope. This is a key aspect of how angular

 *
 * MVC components in angular:
 *
 * * Model — The Model is data in scope properties; scopes are attached to the DOM.
 * * View — The template (HTML with data bindings) is rendered into the View.
 * * Controller — The `ng:controller` directive specifies a Controller class; the class has
 *   methods that typically express the business logic behind the application.
 *
 * Note that an alternative way to define controllers is via the `{@link angular.service.$route}`
 * service.
 *
 * @element ANY
 * @param {expression} expression Name of a globally accessible constructor function or an
 *     {@link guide/dev_guide.expressions expression} that on the current scope evaluates to a
 *     constructor function.
 *
 * @example
 * Here is a simple form for editing user contact information. Adding, removing, clearing, and
 * greeting are methods declared on the controller (see source tab). These methods can
 * easily be called from the angular markup. Notice that the scope becomes the `this` for the
 * controller's instance. This allows for easy access to the view data from the controller. Also
 * notice that any changes to the data are automatically reflected in the View without the need
 * for a manual update.

 * expression changes.
 *
 * Typically, you don't use `ng:bind` directly, but instead you use the double curly markup like

 * `<span ng:bind="expression"></span>` when the template is compiled.
 *

 * @param {expression} expression {@link guide/dev_guide.expressions Expression} to evaluate.
 *
 * @example
 * Enter a name in the Live Preview text box; the greeting below the text box changes instantly.

 *
 * @description
 * The `ng:bind-attr` attribute specifies that a
 * {@link guide/dev_guide.templates.databinding databinding}  should be created between a particular
 * element attribute and a given expression. Unlike `ng:bind`, the `ng:bind-attr` contains one or
 * more JSON key value pairs; each pair specifies an attribute and the
 * {@link guide/dev_guide.expressions expression} to which it will be mapped.
 *
 * Instead of writing `ng:bind-attr` statements in your HTML, you can use double-curly markup to
 * specify an <tt ng:non-bindable>{{expression}}</tt> for the value of an attribute.
 * At compile time, the attribute is translated into an `<span ng:bind-attr="{attr:expression}"/>`
 *
 * The following HTML snippet shows how to specify `ng:bind-attr`:
 * <pre>
 *   <a href="http://www.google.com/search?q={{query}}">Google</a>
 * </pre>
 *
 * During compilation, the snippet gets translated to the following:
 * <pre>
 *   <a ng:bind-attr='{"href":"http://www.google.com/search?q={{query}}"}'>Google</a>
 * </pre>
 *
 * @element ANY
 * @param {string} attribute_json one or more JSON key-value pairs representing

 *    <tt ng:non-bindable>{{expression}}</tt>s. Any number of

/**
 * @ngdoc directive
 * @name angular.directive.ng:cloak
 *
 * @description
 * The `ng:cloak` directive is used to prevent the Angular html template from being briefly
 * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
 * directive to avoid the undesirable flicker effect caused by the html template display.
 *
 * The directive can be applied to the `<body>` element, but typically a fine-grained application is
 * prefered in order to benefit from progressive rendering of the browser view.
 *
 * `ng:cloak` works in cooperation with a css rule that is embedded within `angular.js` and
 *  `angular.min.js` files. Following is the css rule:
 *
 * <pre>
 * [ng\:cloak], .ng-cloak {
 *   display: none;
 * }
 * </pre>
 *
 * When this css rule is loaded by the browser, all html elements (including their children) that
 * are tagged with the `ng:cloak` directive are hidden. When Angular comes across this directive
 * during the compilation of the template it deletes the `ng:cloak` element attribute, which
 * makes the compiled element visible.
 *
 * For the best result, `angular.js` script must be loaded in the head section of the html file;
 * alternatively, the css rule (above) must be included in the external stylesheet of the
 * application.
 *
 * Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they
 * cannot match the `[ng\:cloak]` selector. To work around this limitation, you must add the css
 * class `ng-cloak` in addition to `ng:cloak` directive as shown in the example below.
 *
 * @element ANY
 *
 * @example
   <doc:example>
     <doc:source>
        <div id="template1" ng:cloak>{{ 'hello' }}</div>
        <div id="template2" ng:cloak class="ng-cloak">{{ 'hello IE7' }}</div>

 * @description
 * The most common widgets you will use will be in the form of the
 * standard HTML set. These widgets are bound using the `name` attribute
 * to an expression. In addition, they can have `ng:validate`, `ng:required`,
 * `ng:format`, `ng:change` attribute to further control their behavior.

 * @name angular.directive.ng:options
 *
 * @description
 * Dynamically generate a list of `<option>` elements for a `<select>` element using an array or
 * an object obtained by evaluating the `ng:options` expression.
 *
 * When an item in the select menu is select, the value of array element or object property
 * represented by the selected option will be bound to the model identified by the `name` attribute
 * of the parent select element.
 *
 * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
 * be nested into the `<select>` element. This element will then represent `null` or "not selected"
 * option. See example below for demonstration.
 *
 * Note: `ng:options` provides iterator facility for `<option>` element which must be used instead
 * of {@link angular.widget.@ng:repeat ng:repeat}. `ng:repeat` is not suitable for use with
 * `<option>` element because of the following reasons:
 *
 *   * value attribute of the option element that we need to bind to requires a string, but the
 *     source of data for the iteration might be in a form of array containing objects instead of
 *     strings
 *   * {@link angular.widget.@ng:repeat ng:repeat} unrolls after the select binds causing
 *     incorect rendering on most browsers.
 *   * binding to a value not in list confuses most browsers.
 *
 * @element select
 * @param {comprehension_expression} comprehension in one of the following forms:

 *     * `select` **`as`** `label` **`group by`** `group` **`for`** `value` **`in`** `array`
 *   * for object data sources:

 *     * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
 *     * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`

 *
 * Where:
 *
 *   * `array` / `object`: an expression which evaluates to an array / object to iterate over.
 *   * `value`: local variable which will refer to each item in the `array` or each property value
 *      of `object` during iteration.
 *   * `key`: local variable which will refer to a property name in `object` during iteration.
 *   * `label`: The result of this expression will be the label for `<option>` element. The
 *     `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
 *   * `select`: The result of this expression will be bound to the model of the parent `<select>`
 *      element. If not specified, `select` expression will default to `value`.
 *   * `group`: The result of this expression will be used to group options using the `<optgroup>`
 *      DOM element.

/**
 * @workInProgress
 * @ngdoc widget
 * @name angular.widget.@ng:repeat
 *
 * @description
 * The `ng:repeat` widget instantiates a template once per item from a collection. The collection is
 * enumerated with the `ng:repeat-index` attribute, starting from 0. Each template instance gets
 * its own scope, where the given loop variable is set to the current collection item, and `$index`
 * is set to the item index or key.
 *
 * Special properties are exposed on the local scope of each template instance, including:
 *
 *   * `$index` – `{number}` – iterator offset of the repeated element (0..length-1)
 *   * `$position` – `{string}` – position of the repeated element in the iterator. One of:
 *        * `'first'`,
 *        * `'middle'`
 *        * `'last'`
 *
 * Note: Although `ng:repeat` looks like a directive, it is actually an attribute widget.
 *
 * @element ANY
 * @param {string} repeat_expression The expression indicating how to enumerate a collection. Two
 *   formats are currently supported:
 *
 *   * `variable in expression` – where variable is the user defined loop variable and `expression`
 *     is a scope expression giving the collection to enumerate.
 *
 *     For example: `track in cd.tracks`.
 *
 *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
 *     and `expression` is the scope expression giving the collection to enumerate.
 *
 *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
 *
 * @example
 * This example initializes the scope to a list of names and
 * then uses `ng:repeat` to display every person:
    <doc:example>
      <doc:source>
        <div ng:init="friends = [{name:'John', age:25}, {name:'Mary', age:28}]">

 * @ngdoc widget
 * @name angular.widget.ng:view
 *
 * @description
 * # Overview
 * `ng:view` is a widget that complements the {@link angular.service.$route $route} service by
 * including the rendered template of the current route into the main layout (`index.html`) file.
 * Every time the current route changes, the included view changes with it according to the
 * configuration of the `$route` service.
 *
 * This widget provides functionality similar to {@link angular.widget.ng:include ng:include} when
 * used like this:
 *
 *     <ng:include src="$route.current.template" scope="$route.current.scope"></ng:include>
 *
 *
 * # Advantages
 * Compared to `ng:include`, `ng:view` offers these advantages:
 *
 * - shorter syntax
 * - more efficient execution
 * - doesn't require `$route` service to be available on the root scope
 *
 *
 * @example

/**
 * @ngdoc widget
 * @name angular.widget.ng:pluralize
 *
 * @description
 * # Overview
 * ng:pluralize is a widget that displays messages according to en-US localization rules.
 * These rules are bundled with angular.js and the rules can be overridden
 * (see {@link guide/dev_guide.i18n Angular i18n} dev guide). You configure ng:pluralize by
 * specifying the mappings between
 * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
 * plural categories} and the strings to be displayed.
 *
 * # Plural categories and explicit number rules
 * There are two
 * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
 * plural categories} in Angular's default en-US locale: "one" and "other".
 *
 * While a pural category may match many numbers (for example, in en-US locale, "other" can match
 * any number that is not 1), an explicit number rule can only match one number. For example, the
 * explicit number rule for "3" matches the number 3. You will see the use of plural categories
 * and explicit number rules throughout later parts of this documentation.
 *
 * # Configuring ng:pluralize
 * You configure ng:pluralize by providing 2 attributes: `count` and `when`.
 * You can also provide an optional attribute, `offset`.
 *
 * The value of the `count` attribute can be either a string or an {@link guide/dev_guide.expressions
 * Angular expression}; these are evaluated on the current scope for its binded value.
 *
 * The `when` attribute specifies the mappings between plural categories and the actual
 * string to be displayed. The value of the attribute should be a JSON object so that Angular
 * can interpret it correctly.
 *
 * The following example shows how to configure ng:pluralize:
 *
 * <pre>
 * <ng:pluralize count="personCount"
                 when="{'0': 'Nobody is viewing.',
 *                      'one': '1 person is viewing.',
 *                      'other': '{} people are viewing.'}">
 * </ng:pluralize>
 *</pre>
 *
 * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
 * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
 * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
 * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
 * show "a dozen people are viewing".
 *
 * You can use a set of closed braces(`{}`) as a placeholder for the number that you want substituted
 * into pluralized strings. In the previous example, Angular will replace `{}` with
 * <span ng:non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
 * for <span ng:non-bindable>{{numberExpression}}</span>.
 *
 * # Configuring ng:pluralize with offset
 * The `offset` attribute allows further customization of pluralized text, which can result in
 * a better user experience. For example, instead of the message "4 people are viewing this document",
 * you might display "John, Kate and 2 others are viewing this document".
 * The offset attribute allows you to offset a number by any desired value.
 * Let's take a look at an example:
 *
 * <pre>
 * <ng:pluralize count="personCount" offset=2
 *               when="{'0': 'Nobody is viewing.',
 *                      '1': '{{person1}} is viewing.',
 *                      '2': '{{person1}} and {{person2}} are viewing.',
 *                      'one': '{{person1}}, {{person2}} and one other person are viewing.',
 *                      'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
 * </ng:pluralize>
 * </pre>
 *
 * Notice that we are still using two plural categories(one, other), but we added
 * three explicit number rules 0, 1 and 2.
 * When one person, perhaps John, views the document, "John is viewing" will be shown.
 * When three people view the document, no explicit number rule is found, so
 * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
 * In this case, plural category 'one' is matched and "John, Marry and one other person are viewing"
 * is shown.
 *
 * Note that when you specify offsets, you must provide explicit number rules for
 * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
 * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
 * plural categories "one" and "other".
 *
 * @param {string|expression} count The variable to be bounded to.
 * @param {string} when The mapping between plural category to its correspoding strings.
 * @param {number=} offset Offset to deduct from the total number.
 *
 * @example
    <doc:example>
      <doc:source>
        Person 1:<input type="text" name="person1" value="Igor" /><br/>
        Person 2:<input type="text" name="person2" value="Misko" /><br/>
        Number of People:<input type="text" name="personCount" value="1" /><br/>

        <!--- Example with simple pluralization rules for en locale --->
        Without Offset:
        <ng:pluralize count="personCount"
                      when="{'0': 'Nobody is viewing.',
                             'one': '1 person is viewing.',
