+// CLASS DESCRIPTION (MItMeshEdge)
+//
+//	This class is the edge 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 edges for the polygon.  When a component is given
+//	this iterator will iterate over the edges specified in the component.
+//	When iterating over components a DAG path to the polygon must also be
+//	supplied.
