THIS IS NOT A FULL VERSION!

I am re-writing this addon from scratch. That means I have to re-add every feature, one by one. The old code was getting
old, and had grown far more confusing than I was willing to accept. This new version, when finished, should hopefully be
much more logically written. Ideally, you won't notice much of a difference from the old one. I have uploaded this mostly
for my own benefit.

As for the saved data regarding nodes, this should - once everything is finished - still be exactly as it was before. The
minimap tracking will likely go through some major refactoring just like everything else, but the saved data is formatted
in a way I'm pretty happy with.
