MapDiff: A small library that computes the difference between two maps

Hey @OvermindDL1! Please do tell me more about your ‘more specialized one’. And also, I’m of course going to try to keep the Functional Reactive Programming layer as separate as possible from the WxWidgets layer, so hopefully it will be possible to swap one rendering backend for another.

But this is all still completely theoretical right now, of course :grin:.
