// *****************************************************************************
//
// CLASS DESCRIPTION (MFnMotionPath)
//
//	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.
