ENN Incubator

The enn-incubator repo was used to develop a number of different projects which have since been split out into their own repos:

• entity-gym: Abstraction over reinforcement learning environments that represent observations as lists of structured objects.
• enn-trainer: PPO training loop for entity-gym environments.
• rogue-net: Ragged batch transformer implementation that accepts variable length lists of structured objects as inputs.
• enn-zoo: Collection of entity gym bindings for different environments.
