//! \brief Function set for block add or removal of keys.
/*!
   Certain keyframe editing operations work on group of keys rather than
   an single key. These operations require this function set to
   retrieve changes.

   Function set for reading a block of keyframe changes. They are used
   internally to set a large group of keys quickly. Because changes
   occur in groups using base class keyframe methods on this derived
   class do not make sense.  Therefore, methods describing where the
   block of keys were added or removed are available though methods on
   this class.
