/**
Handles groups of other animations.

When it is appropriate to have several animations starting and stopping
together, add them all to an animation group and control them through that.

In addition to making the code easier to both read and write, the animation
group handles synchronisation issues which can occur when issuing a sequence
of asynchronous requests.

Care must be taken to remove an animation from any groups it may have been
added to before deleting it.
