I'm not going to use GitHub Pages after all, because it is causing more problems than it is helping. All I really wanted was a way to host live JavaScript browser examples. I will find my own way of hosting just those. The main problem is that GitHub pages uses a different flavor of Markdown than GitHub. This makes it really difficult to get something that works right across both. In general, it doubles how much stuff I have to look at when I make a cosmetic change. So I have already turned off GitHub Pages on this repo, and this commit removes all links and references to it.

To execute, run the command:
