;; Bounce a single ball around the screen.
;; IMPORTANT:
;; This problem set will form the basis for problem sets 4 and 5 as well.
;; You are strongly advised to put in the effort to do well on this
;; problem set so that you then have an easier time with problem sets
;; 4 and 5.
;;
;; For this problem set you must complete the design of a world program.
;; The complete program must have the following behaviour:
;; - there is a green background, with a single white ball
;; bouncing around inside that box
;; - when the ball hits the top/right/bottom/left of the box it
;; bounces in the usual way a ball would bounce off of a wall
;; - clicking the mouse replaces the ball with a new ball, at the
, ;; current mouse position, and with a small random x,y velocity
;;
;; Note that we are giving you significant help in the starter file.
;; There is a complete data design, some complete helper functions, as
;; well as a some wish list entries. You absolutely MUST
;; - not edit any of the complete design elements we give you
;; - complete the wish list entries we give you, and do so in a way
;; that is consistent with the rest of the design we give you
;; - must use the helpers we give you as part of your solution
;;
;; We recommend that you begin by first going through the entire file
;; understand what is already complete and what you need to complete.
