ISLocalToGlobalMappingRegister

Adds a method for applying a global to local mapping with an ISLocalToGlobalMapping

#include "petscis.h"  
PetscErrorCode  ISLocalToGlobalMappingRegister(const char sname[],PetscErrorCode (*function)(ISLocalToGlobalMapping))

Not Collective

	sname	- name of a new method
	routine_create	- routine to create method context

ISLocalToGlobalMappingRegister() may be called multiple times to add several user-defined mappings.

   ISLocalToGlobalMappingRegister("my_mapper",MyCreate);

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

    ISLocalToGlobalMappingSetType(ltog,"my_mapper")

or at runtime via the option

    -islocaltoglobalmapping_type my_mapper
