/* Answer these questions
   1) Why are x and y initialized but not h & w
   2) Why do we need this.h = h, but not w = wid?
   3) Do you think the constructor makes sense as written,
       why or why not?
   4) Move only moves by one pixel, modify it to take a 
      a paramenter from the constructor.
   5) Write a method to change the speed of the circle, including negative 
      speed.
