/**
 * 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.
