-- digtron group numbers:
-- 1 - generic digtron node, nothing special is done with these. They're just dragged along.
-- 2 - inventory-holding digtron, has a "main" inventory that the digtron can add to and take from.
-- 3 - digger head, has an "execute_dig" method in its definition
-- 4 - builder head, has a "test_build" and "execute_build" method in its definition
-- 5 - fuel-holding digtron, has a "fuel" invetory that the control node can draw fuel items from. Separate from general inventory, nothing gets put here automatically.
-- 6 - holds both fuel and main inventories
-- 7 - holds batteries (RE Battery from technic) to provide clean renewable power
-- 8 - connects to adjacent HV technic cable
-- 9 - connects to pipeworks, auto-ejects mined items
