 *   The <c>YWatchdog</c> class allows you to drive a Yoctopuce watchdog.
 * <para>
 *   A watchdog works like a relay, with an extra timer that can automatically
 *   trigger a brief power cycle to an appliance after a preset delay, to force this
 *   appliance to reset if a problem occurs. During normal use, the watchdog timer
 *   is reset periodically by the application to prevent the automated power cycle.
 *   Whenever the application dies, the watchdog will automatically trigger the power cycle.
 *   The watchdog can also be driven directly with <c>pulse</c> and <c>delayedPulse</c>
 *   methods to switch off an appliance for a given duration.
