class QgsVectorFileWriter : QgsFeatureSink
{
%Docstring
A convenience class for writing vector files to disk.
There are two possibilities how to use this class:
1. static call to QgsVectorFileWriter.writeAsVectorFormat(...) which saves the whole vector layer
2. create an instance of the class and issue calls to addFeature(...)
