Fixed point iterator improvements, + some linting

1. Cyclic Flow can now figure out where your parameter is in the equality constraint equations, so you no longer have to be careful to put the equations in the right order. Both A=B and B=A are valid now.

2. Cleaned out some extra storage of the convergence history in the fixed point iterator. It is not needed since eq constraints log to the case recorder.

3. Another benchmark added, but nothing has been sped up.

4. Some linting here and there.
