    \brief The QLidReading class holds readings from the Lid sensor.

    A normal laptop has what we call a front lid.

    If the laptop can be converted to a tablet by rotating or closing the lid
    where the display is out, this is known as a back lid.

    \section2 QLidReading Units
    The Lid sensor can detect if a device's lid is closed or not. A lid can be a laptop,
    a laptop that converts to a tablet, or even a cover for a tablet or phone.

    of a QSensorReading.
