find the heading between two geographic coordinates based on http://stackoverflow.com/questions/3809337/calculating-bearing-between-two-cllocationcoordinate2ds

	// from: current location
	float fLat = (currentLocation.coordinate.latitude / 180.0) * M_PI;
	float fLng = (currentLocation.coordinate.longitude / 180.0) * M_PI;

	// to: waypoint location
	float tLat = (waypoint.locationLat / 180.0) * M_PI;
	float tLng = (waypoint.locationLon / 180.0) * M_PI;

	// calculate it!
	float locationHeading = atan2(sin(tLng-fLng)cos(tLat), cos(fLat)sin(tLat)-sin(fLat)cos(tLat)cos(tLng-fLng));
