  * Javascript for omnibox.html, served from chrome://omnibox/
  * This is used to debug omnibox ranking.  The user enters some text
  * into a box, submits it, and then sees lots of debug information
  * from the autocompleter that shows what omnibox would do with that
  * input.
  *
  * The simple object defined in this javascript file listens for
  * certain events on omnibox.html, sends (when appropriate) the
  * input text to C++ code to start the omnibox autcomplete controller
  * working, and listens from callbacks from the C++ code saying that
  * results are available.  When results (possibly intermediate ones)
  * are available, the Javascript formats them and displays them.
