Astronomy: Effemeridi (Ephemeris)

[salvomic]

New version!
thanks to Marcel and RoadRunner, this version check if the app Astro Lab 4 is installed, and if yes, it uses to calculate planets, the app, with much more precision, otherwise it use the old method, with a few arc seconds (in some cases arc minutes) of "error" (very few, however).

Added also other printing improvements (thanks Road!): now the user can tap or drag on screen when the printing results are given, to get other pages...

Improved routine to get phase, illumination, magnitudo of planets.
Improved routine to get phase, illumination, magnitudo of the Moon, also giving "selenographic phase angle", angle of the illuminated limb (χ) and cuspis of the illuminated part.
Exported new functions:
- to calculate Stellar composite magnitudo (giving a list of magnitudes)
- to calculate Apparent and absolute magnitudo for 18 asteroids and comets (giving distance from Sun, distance from Earth and a list with the date (i.e. {2015,7,22}) )
- to calculate Albedo for a few asteroids
- to calculate Semidiameter for an asteroid (giving absolute magnitude and albedo: in the comment inside the program the principal ones).
Other minor bug corrected.

Enjoy!
