Mandelbrot Set Application Usage:

(1) To zoom into the Mandelbrot set, click and drag with the mouse in the Mandelbrot Set Visualization.
(2) After zooming in, use the "<< Back" button to move back to the previous visualization. Now a numbered red rectangle
    will be drawn on the visualization to indicate the previous zoom location.
(3) Click and drag with the mouse in the visualization to zoom in at another location.
(4) Now if you back up, you will see two numbered red rectangles. You can return to one of those zoom locations by choosing
    the matching number from the "Forward" button.
(5) At any time clicking the "Home" button will return the visualization to the starting location which shows the complete
    Mandelbrot set.
(6) Clicking the "Prune" button will remove all zoom locations that are visible in the current visualization. Since pruning
    cannot be undone, you will be asked to confirm that you wish to prune.
(7) Toggle the "Show Zoom Rectangles" checkbox to hide or show the red rectangles.
(8) Select a different colormap to use for the visualization from the Colormap menu button.
