   * <p>Panel is a container that has specific functionality and structural components that make

   * <p>A Panel may contain {@link #bbar bottom} and {@link #tbar top} toolbars, along with separate
   * {@link #header}, {@link #footer} and {@link #body} sections (see {@link #frame} for additional

   * <p>Panel also provides built-in {@link #collapsible expandable and collapsible behavior}, along with
   * a variety of {@link #tools prebuilt tool buttons} that can be wired up to provide other customized
   * behavior.  Panels can be easily dropped into any {@link Ext.Container Container} or layout, and the
   * layout and rendering pipeline is {@link Ext.Container#add completely managed by the framework}.</p>
