I would suggest to have a numeric option for that.

Yes, it does. However, drivers are supposed to support multiple analyses on
different file sets, with reset being called after each analysis. Using the
destructor would only allow to get the data of last pass, but maybe that's ok,
for the beginning, since the umlgraph driver is working differently anyway.
