Minecraft ComputerCraft Modem Composter v2.0 Above and Beyond

---
---Desc: A Composter program which automatically searches Occultism storage
---and moves compostable items to a destination hopper for composting.
---Extracts bonemeal output back into Occultism storage.
---Does not run if bonemeal count > fir_sapling (limiter helps balance inventory).
---This is an upgrade from the first iteration because it interacts with the higher tier Occultism storage
---Review IMPORTANT comments, these are configurables that will likely change based on your setup.
