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.
