/* 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.
