sweep control, iterator object, error norms

[wd15]

Set up at least one example that uses sweep cycles in anger. Determine the future of iterator objects. Maybe abondon. The term objects should have a getResidual(norm = inf, 1, 2 etc) method rather than a getFigureOfMerit() method and it should return something (which it currently does not).

A sweep() method has been introduced that returns residuals and a Stepper class is under experimentation.
