+ * IVehicleBus provides generic interface for various bus interpreters

+ * VehiclePropValue update as if it were generated from real car.

+ * This separates bus implementation details from emulator. For example,
+ * hard-coded rotary controller vendor specific key mapping can separately
+ * run as a service, allowing emulator to be spinned separately from the
+ * particular hardware of interest to be tested at the time.
