Your program has two rectangles.  Each rectangle, if I click on the top,
gets brighter.  If I click on the bottom it gets darker. 

The background is a gradation from bright to dark going left to right.

The program says "yes" or "No" if the two rectangles are the same
brightness.

Your program MUST use a rectangle class.  It MUST have the following methods:
  public rect(int startx, int starty)
     A constructor that places the rectangle at (startx, starty)
 
  public void click(int mouseX,  int mouseY)
     If (mouseX, mouseY) is in the top half of the rectangel, make 
     the rectangle brighter.  
     If it is in the bottom half, make the retangle darker.  

  public int brightness()
     returns how bright the rectangle is.




Points
  One point for each method in the rectangle class.
  One point for clicking brightens.
  One point for darkens.
  One point for saying yes or no.
