  * Exposes the native AwContents class, and together these classes wrap the ContentViewCore

  * primary entry point for the WebViewProvider implementation; it holds a 1:1 object
  * relationship with application WebView instances.
  * (We define this class independent of the hidden WebViewProvider interfaces, to allow
  * continuous build & test in the open source SDK-based tree).
