  TaoSubsetType - PetscInt representing the way TAO handles active sets

- 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.

/*E
    TaoConvergedReason - reason a TAO method was said to have converged or diverged

   Level: beginner

   The two most common reasons for divergence are
$   1) an incorrectly coded or computed gradient or Hessian
$   2) failure or lack of convergence in the linear system (in this case we recommend
$      testing with -pc_type lu to eliminate the linear solver as the cause of the problem).

   Developer Notes:
    this must match petsc/finclude/petsctao.h

       The string versions of these are in TAOConvergedReasons, if you change any value here you must
     also adjust that array.
