// .NAME vtkPVCompositeKeyFrame - composite keyframe.
// .SECTION Description
// 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.
