Integrating Gifs on Github

[MikeLippincott]

          Love these GIF's! As I watched them I wondered about how one might be able to view individual frames with ease in the browser. To this effect, consider the use of [`webm`](https://en.wikipedia.org/wiki/WebM), maybe by converting the GIF's into `webm` from something like [`ffmpeg-python`](https://github.com/kkroening/ffmpeg-python) (or directly from the command line `ffmpeg`). Doing this would I believe add in overlays for stop/play and a timeline, etc (at least in the browser). I haven't tested this from GitHub, so it might be worth seeing if this would work for PR's / GitHub source display.
