 23:   Level: developer

 25:   Adding new methods:
 26:   To add a new method to the registry. Copy this routine and
 27:   modify it to incorporate a call to MatReorderRegister() for
 28:   the new method, after the current list.

 30:   Restricting the choices: To prevent all of the methods from being
 31:   registered and thus save memory, copy this routine and comment out
 32:   those orderigs you do not wish to include.  Make sure that the
 33:   replacement routine is linked before libpetscmat.a.
