/*@C
  MatCoarsenRegisterAll - Registers all of the matrix Coarsen routines in PETSc.

  Not Collective

  Level: developer

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

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