Cleaned up Python bindings to restore functionality:
* StaticPersistence is iterable, its nodes are usable (sign, pair, cycle)
* StaticPersistence knows how to map its nodes into Filtration indices
* moved PythonCmp into utils.h
* minor cosmetic changes

When computing fitness persistence, divide all values by the maximum fitness.
That way it's possible to compare persistence diagrams for runs in different
environments.
