// *****************************************************************************
//
// CLASS DESCRIPTION (MFnLatticeDeformer)
//
//	MFnLatticeDeformer is the function set for lattice deformers.  Lattice
//	deformers use FFDs to deform geometry.
//
//	The lattice deformer is actually a small network of dependency nodes in
//	the dependency graph.  This function set is provided to make
//	manipulation of the network easier.  The main deformer node should be
//	given to this function set as its object.
//
//	There are two lattices associated with a lattice deformer.  There is a
//	base lattice that defines the start position for the lattice.  The
//	second lattice is the version that is modified to deform the geometry.
//	The difference between the two lattices defines the deformation that is
//	applied to the geometry.
//
//	The base lattice is a very simple shape that only defines a box in
//	space.  The base lattice should be modified by using the standard DAG
//	transformation support.  The second deformable lattice has geometry
//	that can be modified using the MFnLattice function set.
//
//	For a piece of geometry to be modified by this deformer, the geometry
//	must be attached to the deformer (use addGeometry method) and the
//	geometry must be contained within the base lattice.  The resetLattice
//	method can be used to make the lattice resize to the bounding box of
//	the attached geometry.
