// CalculateTravelDistanceBetweenPoints
float CALCULATE_TRAVEL_DISTANCE_BETWEEN_POINTS(float x1, float y1, float z1, float x2, float y2, float z2);
Calculates the travel distance between a set of points.
Doesn't seem to correlate with distance on gps sometimes.
This function returns the value 100000.0 over long distances, seems to be a failure mode result, potentially occurring when not all path nodes are loaded into pathfind.
