+ 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
