Implemented Windows testing functions and tested code
-Corrected several syntax errors
-The program successfully simulates ball movement and deflections, accumulates score, and exits when one score == 5
-The code now includes a print_test function and can be visualized in Windows if all four instances of "//" are removed.
-The ball clips the bottom wall and both paddles, and doesn't clip the left and right edges (the opposite of what is desired). The ball doesn't clip the top wall, as intended.
