//! \brief Base class for user defined deformers with per-vertex weights
/*!
 MPxDeformerNode builds on MPxGeometryFilter to allow the creation of deformers
 with per-vertex weights. Built-in Maya nodes which work in this way include
 the jiggle and cluster deformers.

 The weight values can be modified by the user using the set editing window or the percent command.
