\brief Test if all wheels of a vehicle are in the air by querying the wheel query data

\note False is returned if any wheel can reach to the ground.

\note If vehWheelQueryResults.wheelQueryResults is NULL or vehWheelQueryResults.nbWheelQueryResults is 0 then true is returned.
This function does not account for wheels that have been disabled since the last execution of PxVehicleUpdates so it is possible
that wheels disabled more recently than the last call to PxVehicleUpdates report are treated as touching the ground.

\return True if the vehicle is in the air, false if any wheel is touching the ground.
