Creates anything an assembler makes with up to 4 prerequisite components (can be extended for more).
Input materials to left and output to right. Can also use intermediary components in input to speed up the process.
Constant combinator on the right decides the requests.
Screens on left are to see request and can be removed.
May overproduce a few components, but shouldn't clog up. Kinda slow and can be improved :)
