Created skeleton test harness for validating the demo programs.
Created stub moonphase.py.
Copied correct demo program outputs from nodejs; will tweak as needed.
Call the Python demo test harness from the 'run' script.
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.
