     * @ngdoc overview
     * @name angular.filter
     * @namespace Namespace for all filters.
     * @description
     * # Overview
     * Filters are a standard way to format your data for display to the user. For example, you
     * might have the number 1234.5678 and would like to display it as US currency: $1,234.57.
     * Filters allow you to do just that. In addition to transforming the data, filters also modify
     * the DOM. This allows the filters to for example apply css styles to the filtered output if
     * certain conditions were met.
     *
     *
     * # Standard Filters
     *
     * The Angular framework provides a standard set of filters for common operations, including:
     * {@link angular.filter.currency}, {@link angular.filter.json}, {@link angular.filter.number},
     * and {@link angular.filter.html}. You can also add your own filters.
     *
     *
     * # Syntax
     *
     * Filters can be part of any {@link angular.scope} evaluation but are typically used with
     * {{bindings}}. Filters typically transform the data to a new data type, formating the data in
     * the process. Filters can be chained and take optional arguments. Here are few examples:
     *
     * * No filter: {{1234.5678}} => 1234.5678
     * * Number filter: {{1234.5678|number}} => 1,234.57. Notice the “,” and rounding to two
     *   significant digits.
     * * Filter with arguments: {{1234.5678|number:5}} => 1,234.56780. Filters can take optional
     *   arguments, separated by colons in a binding. To number, the argument “5” requests 5 digits
     *   to the right of the decimal point.
     *
     *
     * # Writing your own Filters
     *
     * Writing your own filter is very easy: just define a JavaScript function on `angular.filter`.
     * The framework passes in the input value as the first argument to your function. Any filter
     * arguments are passed in as additional function arguments.
     *
     * You can use these variables in the function:
     *
     * * `this` — The current scope.
     * * `$element` — The DOM element containing the binding. This allows the filter to manipulate
     *   the DOM in addition to transforming the input.
     *
     *
     * @example
     *   //TODO this example current doesn't show up anywhere because the overview template doesn't
     *   //     render it.
     *
     *   The following example filter reverses a text string. In addition, it conditionally makes the
     *   text upper-case (to demonstrate optional arguments) and assigns color (to demonstrate DOM
     *   modification).

         <script type="text/javascript">
           angular.filter.reverse = function(input, uppercase, color) {
             var out = "";
             for (var i = 0; i < input.length; i++) {
               out = input.charAt(i) + out;
             }
             if (uppercase) {
               out = out.toUpperCase();
             }
             if (color) {
               this.$element.css('color', color);
             }
             return out;
           };
         </script>
         <span ng:non-bindable="true">{{"hello"|reverse}}</span>: {{"hello"|reverse}}<br>
         <span ng:non-bindable="true">{{"hello"|reverse:true}}</span>: {{"hello"|reverse:true}}<br>
         <span ng:non-bindable="true">{{"hello"|reverse:true:"blue"}}</span>:
           {{"hello"|reverse:true:"blue"}}

     * //TODO: I completely dropped a mention of using the other option (setter method), it's
     * confusing to have two ways to do the same thing. I just wonder if we should prefer using the
     * setter way over direct assignment because in the future we might want to be able to intercept
     * filter registrations for some reason.

 * @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.
