MatPartitioningRegister

Adds a new sparse matrix partitioning to the matrix package.

#include "petscmat.h" 
PetscErrorCode  MatPartitioningRegister(const char sname[],PetscErrorCode (*function)(MatPartitioning))

Not Collective

	sname	- name of partitioning (for example MATPARTITIONINGCURRENT) or parmetis
	function	- function pointer that creates the partitioning type

   MatPartitioningRegister("my_part",MyPartCreate);

Then, your partitioner can be chosen with the procedural interface via

    MatPartitioningSetType(part,"my_part")

or at runtime via the option

    -mat_partitioning_type my_part
