 *  YGenericSensor Class: GenericSensor control interface, available for instance in the

 *
 * The YGenericSensor class allows you to read and configure Yoctopuce signal
 * transducers. It inherits from YSensor class the core functions to read measures,
 * to register callback functions, to access the autonomous datalogger.
 * This class adds the ability to configure the automatic conversion between the
