Action and ActionQueue

At its heart, Debut is a method of scheduling actions.

• Actions are "run" and that involves executing arbitrary code (functions) - they are not strictly animations
• Actions are run by proxy, through an ActionQueue
• Actions have a concept of direction - they can run forwards or backwards
• Actions run linearly - ie they can run under the assumption that all the events prior to it in the queue have also run
• Actions are assumed to run synchronously, and instantly. Events can opt-in to an asynchronous approach (e.g. for animations)
• Actions can emit events that other actions, or other pieces of code, can listen to
  • For example, they can emit a progress event that other actions can depend on to dictate their progress
• A contract between the Action and the ActionScheduler indicates some parameters that the Action is expected to adhere to
  • The direction of the action
  • Whether the Action should be run instantly (for fast-tracking)
