Yaf_Route_Interface::route — route a request
Yaf_Route_Interface::route() is the only method that a custom route should implement.
if this method return TRUE, then the route process will be end. otherwise,
Yaf_Router will call next route in the route stack
to route request.
This method would set the route result to the parameter request, by calling Yaf_Request_Abstract::setControllerName(), Yaf_Request_Abstract::setActionName() and Yaf_Request_Abstract::setModuleName().
This method should also call Yaf_Request_Abstract::setRouted() to make the request routed at last.
