/**
 * This class represents a preference page that
 * is contributed to the Preferences dialog. By 
 * subclassing <samp>FieldEditorPreferencePage</samp>, we
 * can use the field support built into JFace that allows
 * us to create a page 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.
