/**
* @class Ext.layout.container.Auto
*
* The AutoLayout is the default layout manager delegated by {@link Ext.container.Container} to
* render any child Components when no `{@link Ext.container.Container#layout layout}` is configured into
* a `{@link Ext.container.Container Container}.` AutoLayout provides only a passthrough of any layout calls
* to any child containers.
*
* @example
* Ext.create('Ext.Panel', {
* width: 500,
* height: 280,
* title: "AutoLayout Panel",
* layout: 'auto',
* renderTo: document.body,
* items: [{
* xtype: 'panel',
* title: 'Top Inner Panel',
* width: '75%',
* height: 90
* },
* {
* xtype: 'panel',
* title: 'Bottom Inner Panel',
* width: '75%',
* height: 90
* }]
* });
