TSGLEERegister
register an GLEE scheme by providing the entries in the Butcher tableau
Synopsis
#include "petscts.h"
PetscErrorCode TSGLEERegister(TSGLEEType name,PetscInt order,PetscInt s, PetscInt r,
PetscReal gamma,
const PetscReal A[],const PetscReal B[],
const PetscReal U[],const PetscReal V[],
const PetscReal S[],const PetscReal F[],
const PetscReal c[],
const PetscReal Fembed[],const PetscReal Ferror[],

Not Collective, but the same schemes should be registered on all processes on which they will be used
