-  Helper HTML that redirects Google AppEngine's Channel API to Objective C.
-  This is done by hosting this page in an iOS application.  The hosting
-  class creates a UIWebView control and implements the UIWebViewDelegate
-  protocol.  Then when there is a channel message it is queued in JS,
-  and an IFRAME is added to the DOM, triggering a navigation event
-  |shouldStartLoadWithRequest| in Objective C which can then fetch the
-  message using |popQueuedMessage|.  This queuing is necessary to avoid URL
-  length limits in UIWebView (which are undocumented).
