Add two methods
bool operator==( const GeoDataAlias &other ) const;
bool operator!=( const GeoDataAlias &other ) const;
operator!= should call !operator== inside its implementation.
to GeoDataAlias which implement equality comparision. Add a new unit test in tests/ called TestEquality.cpp (make sure to add it to CMakeLists.txt as well) which creates different GeoDataAlias instances and compares them. Some should be equal, some different, covering various combinations.

Make sure to compile Marble with the BUILD_MARBLE_TESTS=TRUE option enabled and run the test case from the build folder (run tests/TestEquality). 

Extend GeoDataAccurary and add a new operator
bool operator!=( const GeoDataAccuracy &other ) const;
which calls the existing operator== in its implementation. Add test cases for various equal and  unequal instances of GeoDataAccuracy to TestEquality.cpp as well.

Submit a review request at https://git.reviewboard.kde.org with the marble groups as reviewers.
