-/**
- * @class Ext.layout.CardLayout
- * @extends Ext.layout.FitLayout
- * <p>This layout manages multiple child Components, each fitted to the Container, where only a single child Component can be
- * visible at any given time.  This layout style is most commonly used for wizards, tab implementations, etc.
- * This class is intended to be extended or created via the layout:'card' {@link Ext.Container#layout} config,
- * and should generally not need to be created directly via the new keyword.</p>
- * <p>The CardLayout's focal method is {@link #setActiveItem}.  Since only one panel is displayed at a time,
- * the only way to move from one Component to the next is by calling setActiveItem, passing the id or index of
- * the next panel to display.  The layout itself does not provide a user interface for handling this navigation,
- * so that functionality must be provided by the developer.</p>
- * <p>In the following example, a simplistic wizard setup is demonstrated.  A button bar is added
- * to the footer of the containing panel to provide navigation buttons.  The buttons will be handled by a
- * common navigation routine -- for this example, the implementation of that routine has been ommitted since
- * it can be any type of custom logic.  Note that other uses of a CardLayout (like a tab control) would require a
- * completely different implementation.  For serious implementations, a better approach would be to extend
- * CardLayout to provide the custom functionality needed.  Example usage:</p>
- * <pre><code>
-var navHandler = function(direction){
-    // This routine could contain business logic required to manage the navigation steps.
-    // It would call setActiveItem as needed, manage navigation button state, handle any
-    // branching logic that might be required, handle alternate actions like cancellation
-    // or finalization, etc.  A complete wizard implementation could get pretty
-    // sophisticated depending on the complexity required, and should probably be
-    // done as a subclass of CardLayout in a real-world implementation.
-};
-
-var card = new Ext.Panel({
-    title: 'Example Wizard',
-    layout:'card',
-    activeItem: 0, // make sure the active item is set on the container config!
-    bodyStyle: 'padding:15px',
-    defaults: {
-        // applied to each contained panel
-        border:false
-    },

-    bbar: [
-        {

-            disabled: true
-        },
-        '->', // greedy spacer so that the buttons are aligned to each side
-        {
-            id: 'move-next',
-            text: 'Next',
-            handler: navHandler.createDelegate(this, [1])
-        }
