* Parallel reading * Fix win build * Simplifier correctly init nodes * Use generator to open input file(s) * Bit more consistent naming of osm_store files * Make number of locks in attribute store function of number of threads * Small optimization, don't use virtual method calls * Restore nodeListPolygon correct * Don't drop self intersecting polygons
