[GRASS-dev] vector network questions

[Helena Mitasova]

Markus, Michael

I have the new streets data for wake ready, updated based on 2011 data - I will post the location for grass7 with the new streets later today,
you can try it out, if there are still problems there are some other versions that I can try,
