Thank you very much for your contributions. I'd be interested in your response to my current solution as described here:

LOL...and yes, yuck. :) Modifying each sub-file to be a function seems rather beastly, but it certainly does cleanly allow the shared master table to be passed around.

:D

For what it's worth, it is decidedly compact, but it does actually exactly cover the specific problems I faced with my then-current implementation for my project. It was truly real-world.

I am not averse to the suggestion that perhaps the way in which I broke up the files was bad design, though I'm not seeing specifics of where I've made things too tightly coupled or such. If you like, you're welcome to browse the pre-local implementation here:

Thanks again for your feedback.
