Stochastic atom graph, new feature

[InnocentBug]

Convert G-BigSMILES into a graph representation that shows every atom, and the connection between atoms can either be static (always present), stochastic (for repetition in stochastic elements), termination (for ending stochastic elements), or transition for between stochastic elements and regular smiles tokens.

This also comes with an implementation that can convert these graphs directly into normal atom graphs.
