New variation on the equation system solver.
Much simpler to understand. Basically have a variable assignment which
is dynamic and updates with the strategy changes. Similarly have
strategy changes easily invalidate the variable assignment.
This makes them strongly inter-dependent, but simplifies the
implementation considerably. Proving it should be easier like this, too.
