  main.cpp -- Main function for the dashboard controller for a
           car. This controller contains a speedometer, two odometers (total
           and partial distance), a clock, and the pulse generator. The
           pulses are generated by the sensors placed around one of the wheel
           shafts. The rate of pulse generation is determined by the speed of
           the car, which is constant at 120 km/h.  The clock represents the
           real time. The signals in this program are traced. The simulation
           is stopped by the odometers module.

           purpose -- no environment module; multiple modules at one level;
           single processes within each module; input, output and clock
           ports; internal and external signals; asynchronous function and
           thread processes; one clock; tracing.
