forgetted var_dump ?

Hi,

you have some var_dump which are not commented :

* CachedObjectStorageFactory.php : line 233, 234 and 236 ;
* Autoloader.php : line 175, 177, 179 ;

I'm using PHPOffice/PHPExcel with the latest available version with composer ("phpoffice/phpexcel": "dev-develop_2.0.0").
