"""An example of how to design Factorio factories using linear algebra.

This program computes the number of oil refineries, chemical plants, and
assembly machine 2s needed to convert an abundant supply of crude oil and water
into 1.33 rocket fuel per second, the rate needed to satisfy one rocket silo in
the base game, not including modules.

Two abstract vector spaces are constructed: one representing products, and one
