[Tagging] route/forward/backward members in all types of routes

[marc marc]

app can use from+to to choice with relation to use in each direction.
of course de from match the first stop, and to the last stop.
I don't understand what's the problem.

NB: roundtrip=yes mean a circular route, it's not the case of ours.
