[PATCH] handle maps in logic:empty/logic:notEmpty

[Robert Rasmussen]

Small patch related to logic:empty for your consideration.  The intent of 
the change is to make logic:empty (and therefore logic:notEmpty) handle 
a Map in the same way it currently handles a Collection.

Thanks
Robert Rasmussen
