// This class represents a square graphical object.  It is derived from the GRect ACM
// class and adds a color and the restriction of width and height to the same measure.
// It overrides the super methods which allow a client program to change the dimension, 
// forcing the shape to remain square.  The overridden methods are setSize() and setBounds().
