An implementation of SubsetPreconditioner.

The key idea being, use some subset of the rows of the Jacobian as the preconditioner. This CL only implements the preconditioner assuming that the row selection has already been done. How the rows are selected will be left to the user based on their knowledge of the problem. A follow up CL will hook this preconditioner into the rest of the solver.
