+function [] = start_race(track)
+%START_RACE Stops, resets and starts all counters associated with specified
+%track.
+%   All counters, except the pulse train speed counters, associated with a
+%   specified track are stopped and restarted. This resets the current
+%   values of the counters to the initial value (0 for all counters).
+%
+%   At first call the counters just starts, the extra stopping of counters
+%   that are not running does nothing.
