//! \brief Motion path animation function set 
/*!

  This class is used for constructing and manipulating motion path
  animation.

  Motion path animation requires a curve (or surface) and one or more
  other objects.  During the animation, the objects will be moved
  along the curve.

  Setting "follow" for the motion path aligns the object(s) local axis
  to the tangent of the motion path. Banking can also be applied to
  objects.

  Motion path markers are points along the path where the orientation
  and position for the object(s) travelling along the path can be
  specified.
