 * YAnButton Class: analog input control interface, available for instance in the Yocto-Buzzer, the
 * Yocto-Knob, the Yocto-MaxiBuzzer or the Yocto-MaxiDisplay
 *
 * The YAnButton class provide access to basic resistive inputs.
 * Such inputs can be used to measure the state
 * of a simple button as well as to read an analog potentiometer (variable resistance).
 * This can be use for instance with a continuous rotating knob, a throttle grip
 * or a joystick. The module is capable to calibrate itself on min and max values,
 * in order to compute a calibrated value that varies proportionally with the
 * potentiometer position, regardless of its total resistance.
