  TaoSubsetType - PetscInt representing the way TAO handles active sets

+ TAO_SUBSET_SUBVEC - TAO uses PETSc's MatGetSubMatrix and VecGetSubVector
. TAO_SUBSET_MASK - Matrices are zeroed out corresponding to active set entries
- TAO_SUBSET_MATRIXFREE - Same as TAO_SUBSET_MASK, but can be applied to matrix-free operators

  Options database keys:
. -different_hessian - TAO will use a copy of the hessian operator for masking.  By default
                       TAO will directly alter the hessian operator.
