    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.
