/**
 * @class Ext.Component
 * @extends Ext.AbstractComponent
 * <p>Base class for all Ext components.  All subclasses of Component may participate in the automated
 * Ext component lifecycle of creation, rendering and destruction which is provided by the {@link Ext.container.Container Container} class.
 * Components may be added to a Container through the {@link Ext.container.Container#items items} config option at the time the Container is created,
 * or they may be added dynamically via the {@link Ext.container.Container#add add} method.</p>
 * <p>The Component base class has built-in support for basic hide/show and enable/disable and size control behavior.</p>
 * <p>All Components are registered with the {@link Ext.ComponentManager} on construction so that they can be referenced at any time via
 * {@link Ext#getCmp Ext.getCmp}, passing the {@link #id}.</p>
 * <p>All user-developed visual widgets that are required to participate in automated lifecycle and size management should subclass Component.</p>
 * <p>See the <a href="http://sencha.com/learn/Tutorial:Creating_new_UI_controls">Creating new UI controls</a> tutorial for details on how
 * and to either extend or augment ExtJs base classes to create custom Components.</p>
 * <p>Every component has a specific xtype, which is its Ext-specific type name, along with methods for checking the
 * xtype like {@link #getXType} and {@link #isXType}. This is the list of all valid xtypes:</p>

 * It should not usually be necessary to instantiate a Component because there are provided subclasses which implement specialized Component
 * use cases which over most application needs. However it is possible to instantiate a base Component, and it will be renderable,
 * or will particpate in layouts as the child item of a Container:
{@img Ext.Component/Ext.Component.png Ext.Component component}
<pre><code>
    Ext.create('Ext.Component', {
        html: 'Hello world!',
        width: 300,
        height: 200,
        padding: 20,
        style: {
            color: '#FFFFFF',
            backgroundColor:'#000000'
        },
        renderTo: Ext.getBody()
    });
</code></pre>
 *</p>
 *<p>The Component above creates its encapsulating <code>div</code> upon render, and use the configured HTML as content. More complex
 * internal structure may be created using the {@link #renderTpl} configuration, although to display database-derived mass
 * data, it is recommended that an ExtJS data-backed Component such as a {Ext.view.DataView DataView}, or {Ext.grid.Panel GridPanel},
 * or {@link Ext.tree.Panel TreePanel} be used.</p>
 * @constructor
 * @param {Ext.core.Element/String/Object} config The configuration options may be specified as either:

 * <li><b>an element</b> :
 * <p class="sub-desc">it is set as the internal element and its id used as the component id</p></li>
 * <li><b>a string</b> :

 * <li><b>anything else</b> :
