[OSM-talk] Cycleways wiki doc enhanced

[Pieren]

Could some cycleway experimented mappers check and complete this wiki
page that I enhanced with new pictures and examples :

http://wiki.openstreetmap.org/wiki/Bicycle#Cycle_amenagements

I tried to summarize the tagging based on that page and others (e.g.
http://wiki.openstreetmap.org/wiki/Key:access and
http://wiki.openstreetmap.org/wiki/Key:cycleway).
I didn't catch the meaning of two unusual tags in the Key:access page:

For more complex direction dependent restrictions, the postfixes
:backward and :forward can be used on the keys, for example:
    * bicycle:backward=no (when a road has a oneway cycleway next to
it that must be used, and a cyclelane in the other direction)
    * bicycle:backward=yes (when cyclists are allowed to travel in
both directions on a oneway street (but no lane is present))

All comments, remarks are welcome,
