  The overriding of the createCoordinateInformationLine function did not
work. The steps taken to override the function were:

    * Override the createCoordinateInformationLine by deriving a
      SaidsCoordMouseMode from the NavMouseMode2 class, and overriding
      the CreateCoordinateInformationLine function in the derived class
      so it returns a string of UTM or MGRS coordinated

    * Derived Nav Mouse Mode varaible from the SaidsCoordMouseMode
      class instead of the NavMouseMode2 class and add this variable to
      the mouse delegator.

<> private SaidsCoordMouseMode /*NavMouseMode2*/ navMouseMode2;
     navMouseMode2 = new SaidsCoordMouseMode();


    * To set the navMouseNode like is done in openamaps.property file.
      The name of the project is saids, and the SaidsCoordMouseMode is
      the class that is inherited from the NavMouseMode2 class.

<>Code in saids.properties file to set nav mouse mode:

The steps above did not work. Did I do something wrong in the projects
property file?
