Installing Manim

I was hoping to generate some explanatory math videos in the style of 3blue1brown and fortunately the creator Grant Sanderson made his mathematical animation library (Manim) available at 3bib/manim. The repo has instructions for installation on Linux, but as I use Arch it was not as intuitive as I would have liked. As such I am throwing my installation process up here for anyone to duplicate that is running into trouble.
