--- logic: keep a certain amount of certain items in stock in STOCK via
--- RECIPES. while the number is over a certain amount, excess can be used
--- to keep items in stock in EXPORT_STORAGE
--- e.g. lower_lim is 100, upper_lim is 200. export_amt is 100
--- when below 100, go into recipe mode, producing the item
--- when above 200, go into export mode, sending items to export until there are
--- 100 in EXPORT_STORAGE or until at or below 100 in stock (lower_lim)
--- i.e. mode = match (stock_amt, current_mode) {
---          (x, _), x <= lower_lim = RecipeMode;
---          (x, _), x >= upper_lim = ExportMode;
---          (_, curr) = curr;
---      }
--- in order to push the other products through the system, they will be checked
--- and sent if enough of them accrue
