Theme support classes for Spring's web MVC framework. Provides standard ThemeResolver implementations, and a HandlerInterceptor for theme changes.

- If you don't provide a bean of one of these classes as `themeResolver`, a `FixedThemeResolver` will be provided with the default theme name 'theme'.
- If you use a defined `FixedThemeResolver`, you will able to use another theme name for default, but the users will stick on this theme.
- With a `CookieThemeResolver` or `SessionThemeResolver`, you can allow the user to change his current theme.
- Generally, you will put in the themes resource bundles the paths of CSS files, images and HTML constructs.
- For retrieving themes data, you can either use the spring:theme tag in JSP or access via the `RequestContext` for other view technologies.
- The `pagedlist` demo application uses themes
