Will validate a route pattern against the current route.

    /**
     * isValidL4Route
     * 
     * @param  string  $route_url  url that comes from Route::getRoutes() (user/{id})
     * @param  string  $currentUrl url i.e. from Request::path()
     * @return boolean
     */

            return FALSE;
        }

        $route_url = rtrim($route_url, '/');
