// *****************************************************************************
//
// CLASS DESCRIPTION (MItMeshVertex)
//
//	This class is the iterator for polygonal vertices.
//
//	The iterator functions in two modes depending on whether a component
//	is specified. When a component is not given or is NULL the iteration
//	will be over all vertices for the polygon.  When a component is given
//	this iterator will iterate over the vertices specified in the component.
//	When iterating over components a DAG path to the surface must also be
//	supplied.
