// CLASS: MPxDeformerNode
//
// *****************************************************************************
//
// CLASS DESCRIPTION (MPxDeformerNode)
//
// MPxDeformerNode allows the creation of user-defined deformers. A deformer
// is a node which takes any number of input geometries, deforms them and
// places the output into the output geometry attribute.
//
// For more information, please see the built-in documentation
// in MPxDeformerNode.cpp.
