/**
 There are two possibilities how to use this class:
 1. static call to QgsVectorFileWriter::writeAsShapefile(...) which saves the whole vector layer
 2. create an instance of the class and issue calls to addFeature(...)

 Currently supports only writing to shapefiles, but shouldn't be a problem to add capability
 to support other OGR-writable formats.
