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

Subject: Remove maintenance of "lazy decomposition"
Message-Id: <8a14b4849071f910-0-artemis@metatron>
resolution: fixed
The maintenance of "lazy decomposition" (added in [a0736dd3c671]) is
incorrect (due to original theoretical errors). Remove it completely.
