-* Field split with nonlinear solver [MATT]
-
-  Matt created MyMatGetSubMatrix() in Solver.cc to retrieve the
-  preconditioner. Currently this generates a segfault when using the
-  nonlinear solver with field split.
-
-  PREVIOUS NOTES
-
-    The custom preconditioner is not being used in the nonlinear
-    solve. The error appears to be in SolverNonlinear.cc::solve where
-    we set the KSP operator. The _precondMatrix in
-    SolverNonlinear::solve matches the one used in the linear solve.
-
-    - Brad verifies that _precondMatrix at line SolverNonlinear.cc:180
-    is correct. Check that the same Mat pointer is used in ML.
-
-    - FOUND: This is caused by the KSPSetOperators() in SNESSolve_LS()
