     \brief AbstractClipAnimator is the base class for types providing animation playback
     capabilities.

     Subclasses of AbstractClipAnimator can be aggregated by an Entity to
     provide animation capabilities. The animator components provide an
     interface for controlling the animation (e.g. start, stop). Each animator
     type requires some form of animation data such as an AbstractAnimationClip
     as well as a ChannelMapper which describes how the channels in the
     animation clip should be mapped onto the properties of the objects you wish
     to animate.

     The following subclasses are available:
