So... I just committed the initial round of changes to allow attaching a
Preconditioner object to either a linear or nonlinear solver.... and it
works!
I'm already using this in my code with a special preconditioner object to do
fairly complicated solver library (petsc/trilinos) agnostic preconditioning!
So.... I'm going to call mission successful on this one.
There is still more work to do... for instance the hooks need to be put into
the Trilinos set of solvers to use the Preconditioner objects... but that
will come with time.
Let me know if anyone has any problems.
