title: Slim not recogninsing classes from generated-classes file when combined with propel
body: <p>When I run Propel through Slim, the Propel's generated classes are not getting loaded, and i am unable to post or get data from Database. </p>
  
  <p>I have integrated Propel with Slim. All my db code is in Propel files.
  In Foo.php</p>
  
  <pre><code>&lt;?php 
  namespace App;
  //propels required files
  class Foo extends someclass{
    public function foodata()
    {
      echo "hellow propel-Slim";
      $info = new Info();       // this class is in generated_classes
      $info-&gt;setInfodetails('medical info'); 
    }
  }
  ?&gt;
  </code></pre>
  
  <p>In index.php</p>
  
  <pre><code>&lt;?php
    //Slim's required files
    $app-&gt;post("/details/information", "\App\Foo:foodata"); 
  ?&gt;
  </code></pre>
  
  <p>So whenever I run <code>/details/information</code> url it should call the function <code>foodata</code> and insert the data in table info using class <code>Info</code>.
  Instead it will just print the echo statement and give me error. </p>
  
  <pre><code>hellow propel-Slim
  Fatal error: Class 'App\Info' not found in foo.php.
  </code></pre>
