Class SegmentPointComparator

Implements a robust method of comparing the relative position of two points along the same segment. The coordinates are assumed to lie "near" the segment. This means that this algorithm will only return correct results if the input coordinates have the same precision and correspond to rounded values of exact coordinates lying on the segment.
