/* DrawBox allows the user to draw a box on the applet
      using the mouse. The following methods are overridden:

      init()       To set a background color

      mouseDown()  To set the starting point of the box

      mouseDrag()  To "rubberband" the box during drag operation

      paint()      To perform the actual drawing of the box
