/**
- A TechnoArt panel is a drawing surface on which the user can
- sketch curves. The class has a createMenuBar() method that can
- be used to get a menu bar containing drawing commands and options.
- It has a main() routine that enables the class to be run as a
- standalone application; the program just opens a window that
- shows a TechnoArt panel and its menu bar.
- The real point of this example is to demonstrate ArrayList. */
