 * @class Ext.layout.AbsoluteLayout
 * @extends Ext.layout.AnchorLayout
 * <p>This is a layout that inherits the anchoring of <b>{@link Ext.layout.AnchorLayout}</b> and adds the

 * configuration property.  See <tt><b>{@link Ext.Container#layout}</b></tt> for additional details.</p>
 * <p>Example usage:</p>
 * <pre><code>

    title: 'Absolute Layout',
    layout:'absolute',
    layoutConfig: {
        // layout-specific configs go here
        extraCls: 'x-abs-layout-item',
    },
    baseCls: 'x-plain',
    url:'save-form.php',

        x: 60,
        y: 0,
        name: 'to',
        anchor:'100%'  // anchor width by percentage
