body: <p>How can I get User data in the<code>KnpMenuBundle</code>'s Builder?</p>
  
  <p>I know I can get the user data via this line in Controller:</p>
  
  <pre><code>$user = $this-&gt;get('security.context')-&gt;getToken()-&gt;getUser();
  </code></pre>
  
  <p>but I want it to get in my menu builder aswell, so I can put the username in the menu.</p>
