Interface jam.solver.IterativeSolver

public interface interface IterativeSolver
extends Solver
Iterative Solver solves a problem A x - b = 0 for x.
Maybe we should have something like getGradient();
Maybe we should have something like getOperator() and getVector();
Some of these can be implemented in a very general fashion.
