Astronomy: Effemeridi (Ephemeris)

[salvomic]

New version:
implemented a new method to calculate planets coordinates (for more precise result -max ±30', mostly ±2'- use the correspondent functions in Astro Lab 4 that uses another precise method to calculates values);
exported a function to calculate angular separation for two bodies, giving right ascension and declination for both (d = angular separation from the Earth, p = relative separation);
exported also the function to interpolate from three values, giving the "n" factor, useful to get also angular separation (and many other purpose) from a table of RA and dec;
exported Anomaly (mean, eccentric, true) and Moon elongation;
translated other parts;
corrected printing of perihelion and added "argument of perihelion";
corrected (and exported) the tool to get "eccentric anomaly" via Kepler equation...

I must also write a guide: soon.

Enjoy!
