Infinite Minecart Storage

This is a world with my minecart storage system on it. This system uses minecarts stacking on the same rail to store an infinite amount and sorts them with an item sorter that takes items out instead of putting them in the minecarts. It can display up to ten minecarts and two of each requested item. it also has error lights for both requested items and items meant for storage. It could have better timing and it might be best to send items back to the directory and not to the minecarts. This was inspired by SethBling and their video on it.
