Class EdgeIntersection

An 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 label attached to this intersection point applies to the edge from this point forwards, until the next intersection or the end of the edge. The intersection point must be precise.
