Module action_diff 

Serialization-friendly representation of changes to ActionState.

These are predominantly intended for use in networked games, where the server needs to know what the players are doing. They would like a compact, semantically meaningful representation of the changes to the game state without needing to know about things like keybindings or input devices.
