Clearly define our standard for Altitude, Azimuth, Theta, and Phi #44

Open FlorianK13 opened 2 hours ago

here we write:

Azimuth = 0 is North, Azimuth = PI/2 is East. Altitude = 0 is the horizon, Altitude = PI/2 is upwards / Zenith.

But what are phi and theta? From our irradiance data I see that Phi is the azimuth (as it is in [0, 2PI]).

@MartGro and me decided to not use phi and theta anymore in simshady and only talk about azimuth and altitude, as defined above.
