this is really interesting to read imho, thanks for sharing as i missed it in 2016 i guess. It's so nice to get the full, i have this problem, applied smart techniques and got a nice working solution. Fun and interesting read :-). Don't think i'll ever need anything like this ,but it's a great example of tackling a problem with some good methods, and cutting some corners where the output results and expectations allow it. well written and explained.
