<DD><p>Invoked after a node (or a set of siblings) has changed in some
 way. The node(s) have not changed locations in the tree or
 altered their children arrays, but other attributes have
 changed and may affect presentation. Example: the name of a
 file has changed, but it is in the same location in the file
 system.</p>
 <p>To indicate the root has changed, childIndices and children
 will be null. </p>
 
 <p>Use <code>e.getPath()</code> 
 to get the parent of the changed node(s).
 <code>e.getChildIndices()</code>
 returns the index(es) of the changed node(s).</p><DD><DL>
