  Description: Drawing basic shapes such as lines and circles.  Using
  the concepts for lines and circles, we can draw a ball and move it
  in a straight line or circle.  Methods/actions to be completed:

  drawLine
  drawCircle
  drawFilledCircle -- can be used to represent a ball
  moveBall
  moveBallInCircle
