PetscFERegister

Adds a new PetscFE implementation

#include "petscfe.h" 
PetscErrorCode PetscFERegister(const char sname[], PetscErrorCode (*function)(PetscFE))

Not Collective

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

PetscFERegister() may be called multiple times to add several user-defined PetscFEs

    PetscFERegister("my_fe", MyPetscFECreate);

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

    PetscFECreate(MPI_Comm, PetscFE *);
    PetscFESetType(PetscFE, "my_fe");

or at runtime via the option

    -petscfe_type my_fe
