[mkgmap-dev] [patch] clean up point in polygon code

Hi I've made a few changes and fixes to the point in polygon code. Here are the changes included in the attached patch: * Add copyright statements * Correctly assign lat and long to x and y values in MapShape.contains(List<Coord>, Coord, boolean) - This doesn't change the results since the values were used consistently but it's still nice to have it correct. * Clarify comments in MapShape.contains(List<Coord>, Coord, boolean) * Fix comment in MapMaker.makeAreaPOIs(CommandArgs, LoadableMapDataSource) * Add unit test for unclosed shape to ensure all code is exercised. Thanks, Ben
