// \file featureExtIntersectNetNodMet.h
// \brief This file contains the DtFeatureExtentIntersectNetworkNodeMetric 
// class declaration. The purpose of this class is to do a rough selection
// of features based on whether their extent intersects with the given extent
// This metric takes advantage of a quadtree structure such as the vector 
// network's node quadtree.
