Javascript Jupiter as it put it on my website, years ago
Refactor so it'll be easier to add eclipses
Clearer refactoring of moon vs. shadow data
Set z-index of moon images appropriately
if they're on the far side of the planet.
I finally have eclipses and upcoming events more or less working.
Needs a fair amount of cleanup, but checking in so as not to risk
losing the working code.
