There are several time-dependent values used in position calculations, that are not specific to an object.
This class provides storage for these values, and methods for calculating them for a given date. The numbers include solar data like the true/mean solar anomalies and longitudes, the longitude of the Earth's perihelion, the eccentricity of Earth's orbit, the constant of aberration, the obliquity of the Ecliptic, the effects of Nutation (delta Obliquity and delta Ecliptic longitude), the Julian Day/Century/Millenium, and arrays for computing the precession. Store several time-dependent astronomical quantities.
