distance method
Computes the distance between this and another FacetSequence.
@param facetSeq the sequence to compute the distance to @return the minimum distance between the sequences
Implementation
double distance(FacetSequence facetSeq) {
bool isPoint = this.isPoint();
bool isPointOther = facetSeq.isPoint();
double distance;
if (isPoint && isPointOther) {
Coordinate pt = pts.getCoordinate(start!);
Coordinate seqPt = facetSeq.pts.getCoordinate(facetSeq.start!);
distance = pt.distance(seqPt);
} else if (isPoint) {
Coordinate pt = pts.getCoordinate(start!);
distance = computeDistancePointLine(pt, facetSeq, null);
} else if (isPointOther) {
Coordinate seqPt = facetSeq.pts.getCoordinate(facetSeq.start!);
distance = computeDistancePointLine(seqPt, this, null);
} else {
