The previous version of this, "Keep it simple, stupid", used an algorithm which created 3 copies of each atom. We figured out early on, there's an algorithm you can use which is similar, but instead creates 2 copies and an inverse copy. This one is faster due to needing less quicksilver, but the setup became much more difficult to manage. Either way, it's working now, so who cares if I don't know how it works anymore.

Note: I think we can be proud that we're likely the only team that managed to pass all 25 test cases, but fail on others (from an older solve)
