    \class BtSettingModel

    \brief The data model provided to Bluetooth UIs in QT

    BtSettingModel provides APIs for accessing BT local Bluetooth

    settings. In addition, signals from this

    model are provided for being informed of data update. 

    This model is in one dimension (n rows * 1 column), i.e.,

          row 0 (local device name)

          row 1 (power state)

          ...

    The data in this model is non-modifiable from the user interface, 

    determined by the characteristics of Bluetooth, the underline BT software 

    services and the BT application requirements.
