    24 Handles groups of other animations.

    25 

    26 When it is appropriate to have several animations starting and stopping

    27 together, add them all to an animation group and control them through that.

    28 

    29 In addition to making the code easier to both read and write, the animation

    30 group handles synchronisation issues which can occur when issuing a sequence

    31 of asynchronous requests.

    32 

    33 Care must be taken to remove an animation from any groups it may have been

    34 added to before deleting it.
