+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.
