/*!

   Keyframe delta objects are returned via the
   MAnimMessage::animKeyframeEditedCallback( ... ). They describe
   atomic changes to keyframes as a result of a curve edit
   operation. Refer to the documentation in MAnimMessage class for
   further information.

   Base function set for all keyframe delta objects.  A keyframe delta
   object is generated from the
   MAnimMessage::addAnimKeyframeEditedCallback.
