# CSE 143 Homework 1 (Rectangle-Rama), in Python

#
# This provided main program uses your RectangleManager class.
# It displays a DrawingPanel, creates several random Rectangle objects,
# and adds them to your manager.  It also listens for mouse clicks, notifying
# your rectangle manager when the mouse buttons are pressed.
#
# A left-click raises a rectangle to the top of the Z-order.
# A Shift-left-click lowers a rectangle to the bottom of the Z-order.
# A right-click (or a Ctrl-left-click for Mac people) deletes a rectangle.
# A Shift-right-click (or a Shift-Ctrl-left-click for Mac people) deletes 
# all rectangles touching the mouse point.
