/** Part of a small example showing basic use of JToolBar.
 *  Creates a small dockable toolbar that is supposed to look
 *  vaguely like one that might come with a Web browser.
 *  Makes use of ToolBarButton, a small extension of JButton that
 *  shrinks the margins around the icon and puts text label, if
 *  any, below the icon.
