 * This singleton dispatches requests to the appropriate plugin Controller.
 *
 * Piwik uses this class for all requests that go through **index.php**. Plugins can
 * use it to call controller actions of other plugins.
 *
 * ### Examples
 *
 * **Forwarding controller requests**
 *
 *     public function myConfiguredRealtimeMap()
 *     {
 *         $_GET['changeVisitAlpha'] = false;
 *         $_GET['removeOldVisits'] = false;
 *         $_GET['showFooterMessage'] = false;
 *         return FrontController::getInstance()->dispatch('UserCountryMap', 'realtimeMap');
 *     }
 *
 * **Using other plugin controller actions**
 *
 *     public function myPopupWithRealtimeMap()
 *     {
 *         $_GET['changeVisitAlpha'] = false;
 *         $_GET['removeOldVisits'] = false;
 *         $_GET['showFooterMessage'] = false;
 *         $realtimeMap = FrontController::getInstance()->dispatch('UserCountryMap', 'realtimeMap');
 *
 *         $view = new View('@MyPlugin/myPopupWithRealtimeMap.twig');
 *         $view->realtimeMap = $realtimeMap;
 *         return $realtimeMap->render();
 *     }
 *
 * For a detailed explanation, see the documentation [here](https://developer.piwik.org/guides/how-piwik-works).
