Computes whether (and where) a given point lies on or near a polyline, within a specified tolerance. If closed, the closing segment between the last and first points of the polyline is not considered.
point - TripKitLatLng!: our needle
closed - Boolean: whether the polyline should be considered closed by a segment connecting the last point back to the first one
geodesic - Boolean: the polyline is composed of great circle segments if geodesic is true, and of Rhumb segments otherwise
toleranceEarth - Double: tolerance (in meters)
Return Int: -1 if point does not lie on or near the polyline. 0 if point is between poly and poly (inclusive), 1 if between poly and poly, ..., poly.size()-2 if between poly[poly.size() - 2] and poly[poly.size() - 1]
