* If the options are set with the Facebook library ($facebook_config) then there can only be one
* "configuration" for these login and logout parameters.
*
* So for example, Auth::check('popup', $this->request); or Auth::check('page', $this->request);
* The difference maybe between the two Auth configurations is the "login_url_options" array values
* of "display" being "page" or "popup" which tells the FB API how to display the login.
*
* We could also pass these options in the configuration under Libraries::add('li3_facebook'), but then
