org.geotools.geometry.iso.topograph2D.EdgeIntersection
Represents a point on an edge which intersects with another edge.
The intersection may either be a single point, or a line segment (in which case this point is the start of the line segment) The intersection point must be precise. @source $URL$

      Edge e = (Edge) i.next();
