PetscDSRegister

Adds a new PetscDS implementation

#include "petscds.h" 
PetscErrorCode PetscDSRegister(const char sname[], PetscErrorCode (*function)(PetscDS))

Not Collective

	name	- The name of a new user-defined creation routine
	create_func	- The creation routine itself

PetscDSRegister() may be called multiple times to add several user-defined PetscDSs

    PetscDSRegister("my_ds", MyPetscDSCreate);

Then, your PetscDS type can be chosen with the procedural interface via

    PetscDSCreate(MPI_Comm, PetscDS *);
    PetscDSSetType(PetscDS, "my_ds");

or at runtime via the option

    -petscds_type my_ds

Not available from Fortran
