 15:   Adding new methods:

 17:   modify it to incorporate a call to MatCoarsenRegister() for
 18:   the new method, after the current list.

 20:   Restricting the choices: To prevent all of the methods from being
 21:   registered and thus save memory, copy this routine and modify it to
 22:   register a zero, instead of the function name, for those methods you
 23:  do not wish to register.  Make sure that the replacement routine is
 24:   linked before libpetscmat.a.
