// CLASS DESCRIPTION (MItMeshPolygon)
//
// This class is the iterator for polygonal surfaces.
//
// 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 polygons for the surface. When a component is given
// this iterator will iterate over the polygons specified in the component.
// When iterating over components a DAG path to the surface must also be
// supplied.
