This is a temporary directory that is being used to enable email and Gmail content to be shown in the UnifiedEmail application This code should only be used for development. For shipping, this code (or something similar) should go in the Gmail/Email overlay of UnifiedEmail. But for now, this allows us to use a single application to test multiple content sources This code is just a shim to register existing accounts (Gmail and Email) from the device with the AccountCacheProvider. All subsequent uris will actually be handled by the appropriate application.
