 * @brief A generic MAVLINK-connected MAV/UAV

 * This class represents one vehicle. It can be used like the real vehicle, e.g. a call to halt()
 * will automatically send the appropriate messages to the vehicle. The vehicle state will also be
 * automatically updated by the comm architecture, so when writing code to e.g. control the vehicle
 * no knowledge of the communication infrastructure is needed.
