Snakecase

[Forthoney]

Largest change is that all modules (i.e. filenames ending in ".py") have been snake cased, which is proper python style. annotation_generation.py also now uses the official importlib. All interfaces remain the same, except the imports would have to be changed to be snake_case by the users of this lib
