/**
 * <PRE>
 * Image manipulating program.  This program illustrates several
 * object-oriented idioms and patterns.  A program similar in
 * functionality is available in C++, for information send email to
 * <a href "mailto:ola@cs.duke.edu">ola@cs.duke.edu</a>
 * <P>
 * functionality: the program allows the you to to display images
 * (gif or jpg, or anything supported by Java's getToolkit().getImage()
 * Images are specified using a file dialog, but a simple modification
 * would allow the user to use an http: URL (currently a file: URL is used)
 * <P>
 * Each image is shown as a full image, with a thumbnail sketch added
 * to the program GUI.  Clicking on the thumbnail makes that image the
 * active image, the program options for manipulating images always
 * act on the active image.
 * <P>
 * Current image processing is simple: reflect horizontally/vertically
 * and invert (change black-to-white or vice-versa, and do the right
 * thing with color pixels, e.g., red = 255 - red).
 * <P>
 * This program is reasonably well-designed, but it is meant to be
 * be used as a teaching program, so students are urged to
 * suggest/make modificiations to improve the design and to increase
 * the functionality of the program
