TracePoint class

A point of a GPS trace, as sent to snapToRoads.

The GT06 and most tracking devices send heading, speed and time along with the position. Giving it only the position wastes half the accuracy of the operation: with speed and heading, the service can tell the frontage road apart from the parallel highway.
