Tutorials/Shulker box storage/Fortune's filter loader

== Notes ==
* The 'chest' B in the schematic must be a barrel, so that a button can be placed on it.
* Empty shulker boxes are loaded into the barrel. The system is then primed by pressing the barrel's button.
* A single item (any item) must be placed into the top-left hopper.
* The hopper pointed into a comparator is where you configure the filter.
* The top-most hopper is part of the item input hopper line that goes through as many multiple filter/loader modules as you like.
