 * When creating your own theme, either extend this class and specify the styles
 * implemented in your theme here, or extend some other theme that has a class
 * file specified (e.g. Reindeer or Runo).

 * All theme class files should follow the convention of specifying the theme
 * name as a string constant <code>THEME_NAME</code>.
