 * NOTES: Use of this class by DP simplification algorithms
 * makes it useless for a TaggedLineSegment to store copies
 * of coordinates. Using pointers would be good enough here.
 * We don't do it to avoid having to break inheritance from 
 * LineSegment, which has copies intead. Wheter LineSegment
 * itself should be refactored can be discussed.
