Callbacks

A Callbacks object is a very simple helper class that stores a list of functions into three distinct categories that can be called in registration order, with the ability to empty the list after it has been traversed.

It exists mostly to add semantic to the code and make it more readable in contexts that behave the like of a Promise.
