title: Swagger PHP and Doctrine Annotation issue
body: <p>I am implementing Swagger-PHP for an API we've built.</p>
  
  <p>Here is a brief recap:</p>
  
  <p><strong>Language</strong>: PHP5.3</p>
  
  <p><strong>Framework</strong>: FuelPHP 1.5.3</p>
  
  <p><strong>Environment</strong>: Local (served with Nginx)</p>
  
  <p>Now I have an API method defined as follow:</p>
  
  <pre><code>/**
   * @SWG\Api(
   *   path="/site/list",
   *   description="Get sites list",
   *   @SWG\Operation(...,
   *      @SWG\Parameter(...),
   *      @SWG\ResponseMessage(...),
   *      @SWG\ResponseMessage(...)
   *   )
   * )
   */
  public function action_run()
  {
      //doing stuff
  }
  </code></pre>
  
  <p>I now try the following (from elsewhere in my application) to generate the JSON:</p>
  
  <pre><code>$swagger = new Swagger\Swagger('my/root/dir');
  $swagger-&gt;getResource('/site/list', array('output' =&gt; 'json'));
  </code></pre>
  
  <p>And that first line here (when instanciating my Swagger class) is throwing me an error:</p>
  
  <blockquote>
    <p>ErrorException [ User Warning ]: [Semantical Error] The class
    "package" is not annotated with @Annotation. Are you sure this class
    can be used as annotation? If so, then you need to add @Annotation to
    the <em>class</em> doc comment of "package". If it is indeed no annotation,
    then you need to add @IgnoreAnnotation("package") to the <em>class</em> doc
    comment of class @Swagger\Annotations\Api.</p>
  </blockquote>
  
  <p>Adding the <code>@IgnoreAnnotation("package")</code> is actually not helping.</p>
  
  <p>I notice the error disappears if I remove the <code>@package</code> from here:</p>

  <p>But that's not a solution.</p>
  
  <p>I'm guessing this is mainly Doctrine-related but I can't seem to figure it out.</p>
  
  <p>Thanks for any tips or ideas on that matter.</p>
