[Tagging] Feature Proposal - RFC - (Hierarchies route=bicycle)

I just did some work on a hierarchy of hiking routes. Can't be done with Id
or Potlatch, the only available tool is JOSM and even with JOSM you'll have
to do extra steps not to break things.
Reverse is seldom a problem with hiking. Nevertheless, one iwn uses some
sections of a national trail (which in turn is built of three parts, which
in turn are built of ca 10 sections each covering about one day's walking
distance). The basic direction of the common sections is reversed for this
iwn. I did not use roles, but simply took reversed copies of the sections
and used those for the iwn.
For biking, roles forward and backward are used on ways in the route
relation, because there's a very limited amount of ways where the forward
and backward route actually differ.
Indication of continuity in higher level routes, could be handy when
sectioning a large single route, but often variants are included,
shortcuts, extra loops, branches...
