[Users] Layertreebuilder has issues when layer removed.

[Phil Scadden]

You should change your function to this:
> tree.getRootNode().cascade(function(node){
>    if (!node.childNodes || node.childNodes.length==0) {
>       node.remove();
>    }
> }
>
That would surely remove the leaf nodes as well as empty group nodes? 
The trick is recognize that the node is a group node rather than a layer 
leaf node.

I never thought of a delay. on remove. Will experiment.
