iter =   0, Function value -0.330579, Residual: 0.728961 
  ---------- Testing Hessian -------------
  Run with -tao_test_hessian_view and optionally -tao_test_hessian <threshold> to show difference
    of hand-coded and finite difference Hessian entries greater than <threshold>.
  Testing hand-coded Hessian, if (for double precision runs) ||J - Jfd||_F/||J||_F is
    O(1.e-8), the hand-coded Hessian is probably correct.
