                  3 %   ChildList=ALLCHILD(HandleList) returns the list of all children 
                  4 %   (including ones with hidden handles) for each handle.  If 
                  5 %   HandleList is a single element, the output is returned in a 
                  6 %   vector.  Otherwise, the output is a cell array.
