* @class vtkPVCompositeKeyFrame
* @brief composite keyframe.
*
* There are many different types of keyframes such as
* vtkPVSinusoidKeyFrame, vtkPVRampKeyFrame etc.
* This is keyframe that has all different types of keyframes
* as internal objects and provides API to choose one of them as the
* active type. This is helpful in GUIs that allow for switching the
* type of keyframe on the fly without much effort from the GUI.
