PetscRandomRegister

Adds a new PetscRandom component implementation

#include "petscsys.h" 
PetscErrorCode  PetscRandomRegister(const char sname[], PetscErrorCode (*function)(PetscRandom))

Not Collective

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

PetscRandomRegister() may be called multiple times to add several user-defined randome number generators

    PetscRandomRegister("my_rand",  MyPetscRandomtorCreate);

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

    PetscRandomCreate(MPI_Comm, PetscRandom *);
    PetscRandomSetType(PetscRandom,"my_random_name");

or at runtime via the option

    -random_type my_random_name

Notes: For an example of the code needed to interface your own random number generator see src/sys/random/impls/rand/rand.c
