Back to the Future
We can't just time-travel around without first making sure our code is pretty and columns are aligned. And keeping lines with at most 80 characters should help if we ever need to review the code while we're stuck in the past. This is my first challenge. I tried being creative and even did a bit of research, so I hope you enjoy it.
