     *
     *      items: [
     *          Ext.create('Ext.form.field.Text', {
     *              fieldLabel: 'Foo'
     *          }),
     *          Ext.create('Ext.form.field.Text', {
     *              fieldLabel: 'Bar'
     *          }),
     *          Ext.create('Ext.form.field.Number', {
     *              fieldLabel: 'Num'
     *          })
     *      ]
     *
     * But by using `xtype`, the above becomes:
     *
     *      items: [
     *          {
     *              xtype: 'textfield',
     *              fieldLabel: 'Foo'
     *          },
     *          {
     *              xtype: 'textfield',
     *              fieldLabel: 'Bar'
     *          },
     *          {
     *              xtype: 'numberfield',
     *              fieldLabel: 'Num'
     *          }
     *      ]
     *
     * When the `xtype` is common to many items, {@link Ext.container.AbstractContainer#defaultType}
     * is another way to specify the `xtype` for all items that don't have an explicit `xtype`:
     *
     *      defaultType: 'textfield',
     *      items: [
     *          { fieldLabel: 'Foo' },
     *          { fieldLabel: 'Bar' },
     *          { fieldLabel: 'Num', xtype: 'numberfield' }
     *      ]
     *
     * Each member of the `items` array is now just a "configuration object". These objects
     * are used to create and configure component instances. A configuration object can be
     * manually used to instantiate a component using {@link Ext#widget}:
     *
     *      var text1 = Ext.create('Ext.form.field.Text', {
     *          fieldLabel: 'Foo'
     *      });
     *
     *      // or alternatively:
     *
     *      var text1 = Ext.widget({
     *          xtype: 'textfield',
     *          fieldLabel: 'Foo'
     *      });
     *
     * This conversion of configuration objects into instantiated components is done when
     * a container is created as part of its {Ext.container.AbstractContainer#initComponent}
     * process. As part of the same process, the `items` array is converted from its raw
     * array form into a {@link Ext.util.MixedCollection} instance.
     *
     * You can define your own `xtype` on a custom {@link Ext.Component component} by specifying
     * the `xtype` property in {@link Ext#define}. For example:
     *
     *     Ext.define('MyApp.PressMeButton', {
     *         extend: 'Ext.button.Button',
     *         xtype: 'pressmebutton',
     *         text: 'Press Me'
     *     });
     *
     * Care should be taken when naming an `xtype` in a custom component because there is
     * a single, shared scope for all xtypes. Third part components should consider using
     * a prefix to avoid collisions.
     *
     *     Ext.define('Foo.form.CoolButton', {
     *         extend: 'Ext.button.Button',
     *         xtype: 'ux-coolbutton',
     *         text: 'Cool!'
     *     });
     *
     * See {@link Ext.enums.Widget} for list of all available xtypes.

     * For example, if this.hierarchyState.hidden == true, it means that either this
     * component, or one of its ancestors is hidden.
     *
     * Hierarchical state management is implemented by chaining each component's
     * hierarchyState property to its parent container's hierarchyState property via the
     * prototype. The result is such that if a component's hierarchyState does not have
     * it's own property, it inherits the property from the nearest ancestor that does.
     *
     * To set a hierarchical "hidden" value:
     *
     *     this.getHierarchyState().hidden = true;
     *
     * It is important to remember when unsetting hierarchyState properties to delete
     * them instead of just setting them to a falsy value.  This ensures that the
     * hierarchyState returns to a state of inheriting the value instead of overriding it
     * To unset the hierarchical "hidden" value:
     *
     *     delete this.getHierarchyState().hidden;
     *
     * IMPORTANT! ALWAYS access hierarchyState using this method, not by accessing
     * this.hierarchyState directly.  The hierarchyState property does not exist until
     * the first time getHierarchyState() is called.  At that point getHierarchyState()
     * walks up the component tree to establish the hierarchyState prototype chain.
     * Additionally the hierarchyState property should NOT be relied upon even after
     * the initial call to getHierarchyState() because  it is possible for the
     * hierarchyState to be invalidated. Invalidation typically happens when a component
     * is moved to a new container. In such a case the hierarchy state remains invalid
     * until the next time getHierarchyState() is called on the component or one of its
     * descendants.
