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