Refined Storage Autocraft

-- Refined Storage Autocraft 1.1
--
-- Run the program with the pathname of the crafts' listing file
-- Crafts file (a craft per line): [item_name] [count]
-- File example: https://pastebin.com/zDrXzfSM

-- Created by SuperZorro
-- Inspired and borrowed code from Nyhillius and thraaawn

-- 1.0.1: Updated to change component.block_refinedstorage_interface to component.refinedstorage_interface after updating opencomputers?
