871c26abde Enforce strict type checking in all Python demo programs. 
Use mypy to check all Python demo programs.
Updated the demos to pass type checking.
There were a couple of small mistakes found, so this was worth the effort.

66eeb3e0a0 Python: Jupiter's moons returned by name 
It makes more sense to report Jupiter's moons with
individually named structure fields rather than an array.
It reduces the overall code and documentation size,
and outside of unit testing, there are few cases
where iterating over an array of moons is more
lucid than using the names of the moons.

This is a breaking change, but hopefully very few
developers are using this function yet.
Fixing the breakage is very simple.

Also added operator overloads for adding and
subtracting StateVector, just like we already had
for Vector.

5a8daba7d5 Added Python demo of calculating Jupiter's moons. 
The demo shows how to correct for light travel
time to render Jupiter's moons as they appear
from the Earth.

Created an addition operator for the Vector
class in the Python code, because it is handy.

Corrected a bug in the string representation
of the Python StateVector class.
