[Tagging] Cycle route relations, networks and refs

The definition of the cycle network you to complain about can be found 
in http://www.radverkehrsnetz.nrw.de/RVN_home01.html. 
You can't break it into routes, it is a network. And ref=NRW is not so 
bad, the complete name would be ref="Radverkehrsnetz NRW". If you think 
that is better ...

The new, junction-node based system is based on routes, for an example 
you may check http://www.openstreetmap.org/relation/4257206

best regards, Kurt
