DOM

This is a DOM implementation for JSAR runtime, it is based on jsdom partially and use TypeScript to implement the living standard.

Notable changes from jsdom:

• Add a base class XSMLBaseDocument which extends from Node, and it's used for SpatialDocument and XSMLShadowRoot.
  • SpatialDocument is used to represent the spatial document context.
  • XSMLShadowRoot is used to represent an interactive DOM tree which could be attached to a spatial object as a dynamic texture.
• Change the Node, Element's ownerDocument to be XSMLBaseDocument instead of Document.

Note: This is not a Web polyfill for JSAR runtime, which will be available for JSAR user-land, for example, the EventTarget polyfill doesn't implemented here which is depended by JSAR runtime itself, too.
