[Tagging] Public Transport Timetables

I'm mostly experimenting to figure out what can work. My initial though was
a relation per route/stop pair, but that means a lot of relations. Then I
was thinking: it would be nice to have an idea about the approximate time
to get to the next stop, which led to what I did now. Taking that idea a
bit further, why stop at only the next stop, if you can describe the whole

I do think we need a plugin to make handling the information easier. I
think it can easily be added to PT_Assistant if we manage to find someone
who can code in JAVA.

What I like about doing it this way, is that it becomes possible to
determine what will be the final stop for the particular bus that passes at
that stop at that time. This is something we didn't have yet.

The other thing that is nice is that we now have a basis to sort the stops
in the route relations on. (atm PT_Assistant has functionality to sort them
along the highways, if they are sorted correctly).

For someone entering the data, it's enough to enter the departures times
for the first stop. If the times between the stops are not known yet, the
roles remain empty at first. Or we could put sequence numbers in there.
About that, I do notice some have the same minute, it would be nice to have
a way to sort the stops based on the times though.

If someone entered the times at a stop somewhere in the middle of the
itinerary a tool can help adapt the times afterwards.

I'm going to try and apply this to this 'route from hell' (47 itinerary
variations!) :

That PDF only describes what itineraries it takes on weekdays outside of
school holidays...
