/*!
 * \brief The ScStwRace class can be used to measure timings of climbing races with multiple lanes at once.
 *
 * The ScStwRace is a container to manage multiple timers at a time and introduces a propper start sequence
 * with start commands ('At your Marks' and 'Ready') and the official IFSC start signal.
 *
 * ## Basic usage:
 *
 * \code
 * ScStwRace race;
 *
 * // add two timers
 * race.addTimer(new ScStwTimer());
 * race.addTimer(new ScStwTimer());
 *
 * // start a race
 * race.start();
 * \endcode
 *
