KSPRegister

Adds a method to the Krylov subspace solver package.

#include "petscksp.h" 
PetscErrorCode  KSPRegister(const char sname[],PetscErrorCode (*function)(KSP))

Not Collective

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

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

   KSPRegister("my_solver",MySolverCreate);

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

    KSPSetType(ksp,"my_solver")

or at runtime via the option

    -ksp_type my_solver

KSP, register
