Agree that it's better to go with defaults and specify the solver on a per-case basis if required, e.g. for the CH demo. |

LU is OK as a default but I would propose removing the MUMPS default, it's not been working consistently well for me recently.
This is more consistent with what was changed in LinearProblem (let PETSc handle defaults).
