/**
 * @class Ext.ReaderLayout
 * @extends Ext.BorderLayout
 * This is a pre-built layout that represents a classic, 5-pane application.  It consists of a header, a primary
 * center region containing two nested regions (a top one for a list view and one for item preview below),
 * and regions on either side that can be used for navigation, application commands, informational displays, etc.
 * The setup and configuration work exactly the same as it does for a {@link Ext.BorderLayout} - this class simply
 * expedites the setup of the overall layout and regions for this common application style.
 * Example:
 <pre><code>
var reader = new Ext.ReaderLayout();
var CP = Ext.ContentPanel;  // shortcut for adding

reader.beginUpdate();
reader.add("north", new CP("north", "North"));
reader.add("west", new CP("west", {title: "West"}));
reader.add("east", new CP("east", {title: "East"}));

reader.regions.listView.add(new CP("listView", "List"));
reader.regions.preview.add(new CP("preview", "Preview"));
reader.endUpdate();
</code></pre>
* @constructor
* Create a new ReaderLayout
* @param {Object} config Configuration options
* @param {String/HTMLElement/Element} container (optional) The container this layout is bound to (defaults to
* document.body if omitted)
