 * YProximity Class: proximity sensor control interface, available for instance in the Yocto-Proximity

 * The YProximity class allows you to read and configure Yoctopuce proximity sensors.
 * It inherits from YSensor class the core functions to read measurements,
 * to register callback functions, and to access the autonomous datalogger.
 * This class adds the ability to setup a detection threshold and to count the
