Edited, Renewed and Revised by 
        Berkay Berabi
        Louis Meile
 
 
To-do- list by Louis Meile and Berkay Berabi for future projects :
- improve AI (SpaceRaceController): 
i) so far bots arent able to evade obstacles. fix that!
ii) bots should be able to use pickups
- game crashes when bot wins the game(this is a huge problem you should work with the log file to find out what the errors are )
- bots rotate while waiting for the countdown to end. make it stop!
- add elements to level file to make it even more fun to play. be creative!
