Updated CodeQL config to ignore source templates,
because they are not syntactically valid source code.
Ignore other stuff that is irrelevant to published
code quality.
Made various fixes based on helpful CodeQL analysis.
I found a paper by James L Hilton (USNO) that provides
formulas for the phase curves of Mercury and Venus that match
the JPL Horizons tool within 0.012 mag.

JPL Horizons data does not include ring aspect for Saturn,
so don't bother plotting the Saturn data.
I already deleted the Saturn data so it's not there anymore.
The JPL Horizons data for Saturn says at the bottom of the file
that it does not include variations due to ring aspect.
Therefore, it is not suitable for my needs.
I realized if I'm going to create regression models of planets,
it will be helpful to have known correct values of heliocentric
distance of the planet also. Will need to figure out what to do
for Saturn's rings.
Not fully validated, but I did tweak Montenbruck/Pfleger
formulas to match JPL Horizons output for 2018-04-27 02:00 UTC.
Still need to implement formulas for Moon and Saturn.
