/** A simple demo for the ColorPicker class.
*
* @name ColorPicker
* @title Colors: a Color Dialog
* @release April 2007
* @blurb This is a Photoshop-style color choosing dialog.
* <p>You can pull some parts of it apart for customization, but out-of-the-box it offers a great interface if you're dealing with a power user.
* <p>Of course: all dialogs are at least slightly evil, and they should be used with care...
* @see <a href="http://javagraphics.blogspot.com/2007/04/jcolorchooser-making-alternative.html">Colors: a Color Dialog</code>
