[Therion] Therion] Get shortest route

[Bruce Mutton]

This was discussed in 2008 in Therion circles.

To be really useful, the user should be able to specify multiple stations,
with the algorithm finding the shortest centreline distance along the
centreline network that passes through all of the specified points.

Outputs to list as noted by Benedikt below, pdf and aven/Loch models.

I don't think so.

Someone was working on it, but I guess it didn't come to anything as that
was 2016:
