12   main-programmer: David Gruetter
13   co-programmer: Benjamin Grauer
14
15   Created by Dave: this file is actually quite similar to player.cc and so is
16   skybox.h similar to player.h
17   With that said, things should be clear:)
18
19   Edited:
20   Bensch: more constructors, changeability, comments...
21   Patrick: giving it the common orxonox style, not much to do... good work Dave!
