[GraphHopper] What are pillar and tower Nodes? Rename to geometry and junction nodes?

[Thi Nguyen]

Hi,

I've been working with graphhopper for about 2 months now and I feel
"tower" and "pillar" are pretty intuitive. IMHO, perhaps better
documentation to show what they really mean would be way more useful.

Without looking at the documentation, I wouldn't know what "junction" and
"geometry" nodes are either.

Best,
Thi
