title: How could visually match 2 trees?
body: <p>I wrote a script that loads data from 2 tables.<br>
  Using this script I need to just match corresponding elements in these 2 columns.</p>
  
  <p>I am using angular-ui-tree for managing columns, but can't come up with an idea how to visually and programmatically match corresponding elements between 2 trees?</p>
  
  <p>Thanks</p>
