/**

 *  CLmkCoordinateEditor extend ClmkFloatEditor's functionality

 *  Implements both latitude and longitude editors.

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

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

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

 *  by cardinal point.

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

 *  are represented by number's sign.
