CharacteristicRegister

Adds a solver to the method of characteristics package.

#include "petsccharacteristic.h" 
PetscErrorCode CharacteristicRegister(const char sname[],PetscErrorCode (*function)(Characteristic))

Not Collective

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

    CharacteristicRegister("my_char", MyCharCreate);

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

    CharacteristicCreate(MPI_Comm, Characteristic* &char);
    CharacteristicSetType(char,"my_char");

or at runtime via the option

    -characteristic_type my_char

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