Don Cross 1558f808e4 MoonLatitudes writes CSV file. MoonVector has larger time span. ...

MoonLatitudes now generates a CSV file for me to study the
ecliptic latitude discrepancy as a function of time.
I can see that it increases away from the year 2000,
and that it is periodic with the Moon's orbit.
This indicates an error in correcting for precession.

Generated new JPL Horizons test data for MoonVector that
covers the years 1900..2100 instead of 1980..2020.
Confirmed that its maximum error is still 1.16 arcsec.
That is error comparing EQJ vectors and ECL vectors.
