title: doctrine2 - generating entities
body: <p>i'm using doctrine2 cli for generating entities.</p>
  
  <p>i have the original classes defined in PHP with docblock.
  when i run the doctrine orm:generate-entities, the new files are created - fields are generate, and methods (setters/getters) are created.</p>
  
  <p>the problem is, i want to copy my own custom methods from the original files (without extending the files).</p>
  
  <p>for example:
  i have skel\Employee.php with:</p>
  
  <pre><code>class Employee {
      /** comments */
      public $key;
      public function myCustomMethod(){
          ....
      }
  }
  </code></pre>
  
  <p>when i run orm:generate-entites, models\Employee.php is created but myCustomMethod() is not copied</p>
  
  <p>is there a way to copy custom commands?</p>
