 * YLightSensor Class: light sensor control interface, available for instance in the Yocto-Light-V4,
 * the Yocto-Proximity or the Yocto-RangeFinder
 *
 * The YLightSensor class allows you to read and configure Yoctopuce light 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 easily perform a one-point linear calibration
 * to compensate the effect of a glass or filter placed in front of the sensor.
 * For some light sensors with several working modes, this class can select the
 * desired working mode.
