- update methods of existing classes - add comment to methods missing in the sip bindings - split up collective sip files into single files and use same directory structure in python/ as in src/ - add a lot of missing classes (some might not make sense because of missing python methods in those classes) - remove some non-existing methods from the header files - add scripts/sipdiff - replace some usages of std::vector and std::set with QVector/QSet
