Towards the finite grammar approximation

Produced a new 3D figure and updated other Poincare section figures.
Showed highly unstable cycle 010 on the return map. I also computed its
topological coordinate. Starting tomorrow, I'll eliminate the binary
cycles with higher topological coordinates and search for the remaining
ones.

I think this approximation will give me "golden mean" cycles, because by
picking 010, I prune 00.
