/**
 *  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.
