/**
* The uri dispatcher is responsible for taking uri's, determining
* the content and routing the opened url to the correct content
* handler.
*
* When you encounter a url you want to open, you typically call
* openURI, passing it the content listener for the window the uri is
* originating from. The uri dispatcher opens the url to discover the
* content type. It then gives the content listener first crack at
* handling the content. If it doesn't want it, the dispatcher tries
* to hand it off one of the registered content listeners. This allows
* running applications the chance to jump in and handle the content.
*
* If that also fails, then the uri dispatcher goes to the registry
* looking for the preferred content handler for the content type
* of the uri. The content handler may create an app instance
* or it may hand the contents off to a platform specific plugin
* or helper app. Or it may hand the url off to an OS registered
* application.
