SNESRegister

Adds a method to the nonlinear solver package.

#include "petscsnes.h"  
PetscErrorCode  SNESRegister(const char sname[],PetscErrorCode (*function)(SNES))

Not collective

	name_solver	- name of a new user-defined solver
	routine_create	- routine to create method context

SNESRegister() may be called multiple times to add several user-defined solvers.

   SNESRegister("my_solver",MySolverCreate);

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

    SNESSetType(snes,"my_solver")

or at runtime via the option

    -snes_type my_solver

Note: If your function is not being put into a shared library then use SNESRegister() instead
