title: how to put an icon on top of jsTree tree
body: <p>so i have a <a href="https://www.jstree.com/" rel="nofollow noreferrer">jsTree</a> tree, and i wish i could put a 'lone star' type icon like this...</p>
  
  <p>at the very top of the tree:</p>
  
  <p><a href="https://i.stack.imgur.com/NAdE5.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NAdE5.jpg" alt="loneStar"></a></p>
  
  <p>jsTree is jquery plugin, that provides interactive trees. It is absolutely free, open source and distributed under the MIT license. jsTree is easily extendable, themable and configurable, it supports HTML &amp; JSON data sources and AJAX loading.</p>
  
  <p>jsTree functions properly in either box-model (content-box or border-box), can be loaded as an AMD module, and has a built in mobile theme for responsive design, that can easily be customized. It uses jQuery's event system, so binding callbacks on various events in the tree is familiar and easy.</p>
