title: Annotation @OrderBy
body: <p>I'm trying to automatically order the results of a report by the ManyToMany annotation <code>@OrderBy</code>:</p>
  
  <pre><code>/**
   * @ORM\ManyToMany(targetEntity="Artist", inversedBy="soundtrack", cascade={"persist", "remove"})
   * @ORM\JoinTable(name="soundtrack_artist")
   * @OrderBy({"name" = "ASC", "surname" = "ASC"})
   **/
  private $artists;
  </code></pre>
  
  <p>but it gives me this error:</p>
  
  <pre><code>[Semantical Error] The annotation "@OrderBy" in property
  Acme\UserBundle\Entity\Soundtrack::$artists was never imported.
  Did you maybe forget to add a "use" statement for this annotation?
  </code></pre>
  
  <p>I tried to add also:</p>
  
  <pre><code>use Doctrine\ORM\Mapping\OrderBy;
  </code></pre>
  
  <p>But the error remains!
  I'm doing something wrong?</p>
