This script deletes all empty layers. In max 2015 (at this time) it can keep ALL nested layers (user prompt) if any one of them has objects on it. In other words, if a user chooses "Yes" at the query, ONLY layers with NO children AND no objects will be deleted. All nested hierarchies are maintained down to the last layer that has objects in it. Choosing "No" at the prompt will unnest all layers and delete all empty layers. When using a version of max prior to 2015, the script will simpy delete any empty layers. There are no nesting options in previous versions of the Layer Manager.
