/*  This applet allows the user to draw 1 fixed-sized square or 1 fixed-sized circle on a 
canvas.  The program will have 2 buttons, 1 labeled "Square" and the other labeled "Circle".
The user clicks on one of the buttons, then clicks on the canvas, where the appropriate figure
is drawn.  Only 1 object is drawn on the canvas at a time and the user must click on 1 of the
buttons after clicking on the canvas in order to draw another object at a different location.
