13   main-programmer: David Gruetter
14   co-programmer: Benjamin Grauer
15
16    Created by Dave: this file is actually quite similar to player.cc and so is
17    skybox.h similar to player.h
18    With that said, things should be clear:)

20    Edited by Bensch: more constructors, changeability, comments...
