CAnimator derived plugin for bitmap frames.

This animator is loaded when the data provider is passing a fixed sequence
of bitmap frames, and a type of "bitmap".  This is the type used by the
CICLAnimationDataProvider.

You do not need to instatiate animators in a client application.  This is
handled by the animation classes.
