/**
 * 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.
