  * @fileoverview This file is the controller for generating extension
  * doc pages.
  *
  * It expects to have available via XHR (relative path):
  *   1) API_TEMPLATE which is the main template for the api pages.
  *   2) A file located at SCHEMA which is shared with the extension system and
  *      defines the methods and events contained in one api.
  *   3) (Possibly) A static version of the current page url in /static/. I.e.
  *      if called as ../foo.html, it will look for ../static/foo.html.
  *
  * The "shell" page may have a renderering already contained within it so that
  * the docs can be indexed.
