// *****************************************************************************
//
// CLASS DESCRIPTION (MPxEmitterNode)
//
// MPxEmitterNode allows the creation and manipulation of dependency graph
// nodes representing emitters.  This is the top level of a hierarchy of
// emitter node function sets.  It permits manipulation of the attributes
// common to all types of emitters.
