    38  *  CLmkCoordinateEditor extend ClmkFloatEditor's functionality

    39  *  Implements both latitude and longitude editors.

    40  *  Underlying floating value is just a value, which user inputs.

    41  *  Its upper limit depends on editor type: latitude or longitude.

    42  *  Lower limit is always 0, because coordinate sign is represented

    43  *  by cardinal point.

    44  *  Number() always returns coordinate in degrees. Cardinal points

    45  *  are represented by number's sign.
