• how to handle output for sulfurs that represent a tag like logs?
• the upper block accepts a filter
  • show the accepted item in world?
  • Model after create sawmill ( I guess it takes an item filter - if it just takes an item that is fine too)
  • IF multiple items are supported by create -> cycle
• by default each output should cycle (like create sawmill
  • but not good for e.g. coal vs charcoal!

#207 makes this obsolete, I think
As long as each actual item gets a sulfur, and "categories" are represented by niters all works
