This is the state of the gh-pages branch…

…before a massive cleanup.

The source repo was a big mess. Needed to be cleaned up and modernized.

At this time `gh-pages` was the only branch.
The new branch called `main` was made from this commit, to contain the
source files and then publish the html to `gh-pages`, to serve at
