/*
For the materials datum, it assumes you need reagents unless specified otherwise. To designate a material that isn't a reagent,
you use one of the material IDs below. These are NOT ids in the usual sense (they aren't defined in the object or part of a datum),
they are simply references used as part of a "has materials?" type proc. They all start with a $ to denote that they aren't reagents.
The currently supporting non-reagent materials. All material amounts are set as the define SHEET_MATERIAL_AMOUNT, which defaults to 100

Don't add new keyword/IDs if they are made from an existing one (such as rods which are made from iron). Only add raw materials.

Design Guidelines
- When adding new designs, check rdreadme.dm to see what kind of things have already been made and where new stuff is needed.
- A single sheet of anything is 100 units of material. Materials besides iron/glass require help from other jobs (mining for
other types of metals and chemistry for reagents).
- Add the AUTOLATHE tag to
