   Note:
   The forward declaration of MF_LowerLevel, below, is all that is 
   needed for MF_TopLevel since it holds a pointer to an instance of
   MF_LowerLevel, not an actual instance.

   Therefore, clients of MF_TopLevel do not see the text of MF_LowerLevel.h
   and are not bound to its implementation.
