// DESCRIPTION:
//
// This plug-in defines both a MEL command and a DG node which computes
// the worldspace position and normal on a poly mesh given a face index,
// a U-parameter, and a V-parameter as input. 
//
// REFERENCES:
//
//  - This plug-in is based on the "pointOnSurface" MEL command and "pointOnSurfaceInfo" node.
//  - The pointOnSubdNode.cpp plug-in example from the Maya Developer Kit was also used for reference.
//
// LAST UPDATED: Oct. 11th, 2001.
//
// COMPILED AND TESTED ON: Maya 4.0 on Windows
