-// This class is the coordinator for dispatching web intents and seeing that
-// return messages are sent to the correct invoking context. The WebContents
-// for the invoking context will create one of these for each intent and hand
-// a pointer to the client WebContentsDelegate code. The WebContentsDelegate
-// code can then read the intent data, create UI to pick the service, and
-// create a new context for that service.
-//
-// At that point, it should call DispatchIntent, which will deliver the intent
-// to the new context. If anything goes wrong during setup, the client
-// should call SendReplyMessage with an error. The dispatcher lives until the
-// SendReplyMessage method is called, which will self-delete the object.
-//
-// The client should also register a reply notification, so it can avoid
-// referencing the dispatcher after other code calls SendReplyMessage, which can
-// happen if, for example, the user closes the delivery context.
