 * This is the AWF integration file for the Joomla! 2.x / 3.x CMS. It allows you to run an AWF application as a Joomla!
 * component. You need to provide the following variables before including this script:
 *
 * @var string $appName The application name, e.g. Foobar for com_foobar. It's also the name of your AWF Application's
 *                      namespace. The admin side in this case will have the namespace FoobarAdmin and component name
 *                      com_foobar
 * @var array $containerOverrides Any variables you want to push to the DI Container
