Prevent myself from running with old Python
...
Since I use an `ELLIPSIS` option that appears to not work under 2.7.

Change main computation routine to a generator
...
This is kind of magic. Because it is now a generator, you have the
option of asking for position, then only proceeding to the velocity if
you need it, without having to repeat the work of getting to that point
again.

Move old Python-format ephemerides to "legacy"
...
Because bare directories with *.py files inside are now considered
packages to Python 3, these directories were being grabbed by the
"import" statement during certain tests, instead of letting Python find
the actual installed ephemerides packages. Bumping them down a level
solves the problem, and also unclutters the top level.

Avoid truncating ephemerides with repeated blocks
...
Before, an ephemeris that (a) had a repeated block of coefficients,
where (b) some of the coefficients did not match, would be silently
truncated at that block instead of getting completely compiled to numpy
arrays. I have rebuilt DE421 since the earlier version of it that I
posted was accidentally truncated by this code.

Add a command to re-fetch build ephemerides
...
This ability allows development to re-commence on a machine after a
quick download of the ephemeris files, instead of having to rebuild
the ephemerides over again from their JPL data sets (that take quite
a long time to download!).

Created a command to upload sdists to S3 since PyPI refuses packages this big.

Added DE421 to the mix, and tried to give them all reasonable docstrings.

Started writing a setup.py to enable distribution of the ephemerides on PyPI, and gave de405 an __init__.py as a first step in that direction.

Got the last of the four major ephemera, DE406, passing its tests by working around a discrepancy between what DE406's header says is the last date in the polynomials, and the actual last date.

Got nutations working! The build script needed to know that nutation only has two components, not three.

Bugfix: the build.py script was pulling the first set of coefficients N times, instead of pulling all N sets of coefficients.

Renamed my fake constants to lowercase, so they are clearly different than the real JPL constants from the header file. And, gave them cooler names.
