Implement preliminary collision
Collision works a bit better
Added printouts

as we can see from running, both balls get the same direction after collision.
Collisions work as intendend
Fix how the camera acts when resizing the window
Change the delta time
Added energy loss/friction and comments/javadoc
Balls are now stored in an array

Instead of doing n^2 loops for seeing which balls collide, we now do (n^2)/2 loops.
Note: I'm not so sure if this actually is so smart as I first thought it to be... :P
If we give the initial array a too big size, this solution might actually not be so good...
Clicking on a ball is like a kick

The ball will get extra speed relative to where the click occurred, ie if you click at the balls upper right, the added speed will be in that direction. The farter away from the balls center one clicks, the more the gain.
Change ball array to an ArrayList
Added javadoc to handleCollission()
2 balls now :(
Produce output when termodynamic laws are broken
Update the touchUp method so it works better

However, I'm not sure if it's completely bug free
Merge branch 'master' of bitbucket.org:MaTachi/dat026
Add names and group number to the files
