/**
 * ZF2 Integration for Whoops
 * @author Balázs Németh <hide@address.com>
 *
 * The Whoops directory should be added as a module to ZF2 (/vendor/Whoops)
 *
 * Whoops must be added as the first module
 * For example:
 *   'modules' => array(
 *       'Whoops',
 *       'Application',
 *   ),
 *
 * This file should be moved next to Whoops/Run.php (/vendor/Whoops/Module.php)
