Iterating to a solution

Iterating to a solution is the core of any simulation. A flow chart of what happens when iterating is shown here:

Iterations are kept track of via the IBiasingSimulationState. Each IBiasingBehavior gets the chance to manipulate the Y-matrix and right-hand side vector, after which a solution is found.

Once the solution does not change significantly (if the error is within tolerances), then the method stops iterating.
