Interfaces
 InterfaceDescription
 ILiveManager Instances receive a callback from GoEngine after each update cycle, allowing managers to more easily perform ongoing processes during animation.
 IManageable Makes udpatable items usable by IManager instances.
 IManager Makes an object compatible with GoEngine.addManager() [This section updated recently!]

What are managers?

Tweens and other animation items are not aware of other items while they run; by contrast, manager classes can monitor and interact with many active items at once.

 IPlayable Defines a standard set of play controls and a play-state property.
 IUpdatable Makes any object compatible with GoEngine.
