The previous implementation of moveObject has now been removed.
Added a TODO.
New function: snapDiff.
Not only is there an other_obj there is now an other_original.
Bit of cleanup of code duplication in moveObject.
Documentation + Extra blank line. - Cleanup.
The simpler overload of moveObject now more closely resembles the interface of the other overload.

That means it returns a boolean and accepts the slave argument.
Added Paddle x Ball and Ball x Ball collision detection.
