title: JsTree v3.0 drag and drop plugin. Reference target node upon dropping
body: <p>I use drag and drop plugin of <a href="http://www.jstree.com/" rel="noreferrer">jsTree</a> library (ver. 3.0)
  With the following code I can bind to the end of drag'n'drop action, but I can not see a way to get the reference to the target node (the node I'm dropping on).</p>
  
  <pre><code>$(document).on('dnd_stop.vakata', function(e, data) {
     // how to get target_node here?
  });
  </code></pre>
