title: how to use different namespaces in a controller in laravel 4.1
body: <p>What I want to do is to use different namespaces in a controller. I have a tree scheme like this:</p>
  
  <pre><code>app/
  app/controllers/
  app/modules/
  app/modules/modulename/
  app/modules/modulename/controllers/
  app/modules/modulename/controllers/modulecontroller.php
  app/modules/modulename/models/
  app/modules/modulename/models/modulemodel.php
  </code></pre>
  
  <p>What I want to do is to call a model from a controller in app/controllers/ folder. Therefore I am supposed to add namespace as follows:</p>
  
  <pre><code>    use App\Modules\Facebook\Controllers\Facebook;
  </code></pre>
  
  <p>The problem is that when I add a namespace and use App::() function at the sametime, I get the following error:</p>
  
  <pre><code>    Class 'App\Modules\Modulename\Controllers\App' not found
  </code></pre>
  
  <p>I think it is looking the <code>App::()</code> function in module folder. How can I solve this problem?</p>
