Latitude/Longitude inversion

[EmilyBourne]

The geo-co-ordinates provided by SUMo are in (Longitude,Latitude) format, however GeoPosition as defined in artery/utility/Geometry.h is in format (latitude,longitude). This means that when the GeoPosition is created as in the function VehicleController::getGeoPosition() (artery/traci/VehicleController.cc: line 38) the longitude is saved as latitude and latitude as longitude

Oops, this is a really unfortunate mistake probably introduced during some code refactoring. I have changed the relevant code fragment to refer to GeoPosition's attributes explicitly by name so this bug is unlikely to be reintroduced. Fixed by 82afb97.
