Extend the GeoDataWriter unit test to test operator== of GeoDataDocument
Review Request #118042 - Created May 7, 2014 and submitted
Implemented saveAndCompareEquality within TestGeoDataWriter which is based on the current function, saveAndCompare. This function compares the actual file and the parsed & written file, using QTextStream's. My implementation uses the newly implemented GeoDataDocument::operator==.
All tests finish as expected, only after making the change proposed here: https://git.reviewboard.kde.org/r/118040/.
