title: Remove from AVL tree example code
body: <p>I am looking into AVL trees and can not seem to find a reference code about removal (either by Googling or from a couple of textbooks I have handy).<br>
  I am not sure why is this, but do you know of any reference/example of deletion of AVL in java?<br>
  (I only found this:<a href="http://www.dreamincode.net/forums/topic/214510-working-example-of-avl-tree-remove-method/" rel="noreferrer">avl tree removal</a> which it states in the link that it failed under testing)</p>
