 * This class represents a preference page that is contributed to the Preferences dialog. By subclassing

 * that is small and knows how to save, restore and apply itself.
 * <p>
 * This page is used to modify preferences only. They are stored in the preference store that belongs to the main
 * plug-in class. That way, preferences can be accessed directly via the preference store.
