- 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

There are two possibilities how to use this class:

1. static call to QgsVectorLayerImport::importLayer(...) which saves the whole vector layer
|
|
2. create an instance of the class and issue calls to addFeature(...)
