Help for writing an app (running zones using Karvonnen method)

edit: Sorry, I didn't see the whole second page of comments, so this is less useful now!

I'd say run.karvonnen.js or something like that would be a good bet.

The thing I'm thinking of is there's a file for working out sunset, and then it started being used in a few places, and we had multiple apps providing sunset.js, many of which were different - and obviously we want to avoid that.

If you though it might be used in other apps you could always add it to the modules folder?
