 15:   MatPartitioningRegisterAll - Registers all of the matrix Partitioning routines in PETSc.

 17:   Not Collective

 19:   Level: developer

 21:   Adding new methods:
 22:   To add a new method to the registry. Copy this routine and
 23:   modify it to incorporate a call to MatPartitioningRegister() for
 24:   the new method, after the current list.

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