Add a mesh generator for creating a polyline that follows a nodeset

[GiudGiud]

bunch of heuristics lumped together to make it work.
I somewhat doubt we'll find a way to have a unique perfect solution here, and I also don't doubt that the next time I'll use this I'll add another heuristic for the new case
