title: Laravel: Class not found Exception
body: <p>In my Laravel project, if have a file app/lib/<em>Formatter.php</em>, with an class Formatter.<br>
  From a Controller i am importing this php file using <code>use App\Lib\Formatter;</code>
  In my local development enviroment, I can access methods from the Formatter in my Controller. But when i deploy the laravel project to a share hosting, i can't access Formatter. Laravel returns this error message: </p>
  
  <blockquote>
    <p>"Class 'App\Lib\Formatter' not found"</p>
  </blockquote>
  
  <p>After it works localy, i don't have any idea, why it shouldn't work on shared hosting.</p>
