**** next method routines that you will need to supply.  However,
**** since it doesn't know your system, several things are left to you.
**** Look for comments with `!!!' in them for places you're likely to want
**** to change for your system.  Also, while the layout of the method
**** routines is a commonly useful one, it will not fit all data structures
**** and systems.  Look at this output as a guide to how to write your
**** method routines; a guide that will, in most cases, significantly reduce
**** the amount of typing you need to do.
**** 
**** The code here assumes you've created a file called `mibleaf.h' with
