By default all components that are "state aware" check this class
for state information if you don't pass them a custom state provider. In order for this class
to be useful, it must be initialized with a provider when your application initializes. Example usage:
 <pre><code><i>// <b>in</b> your initialization <b>function</b></i>
init : <b>function</b>(){
   Ext.state.Manager.setProvider(<b>new</b> Ext.state.CookieProvider());
   <b>var</b> win = <b>new</b> Window(...);
   win.restoreState();
}</code></pre><br><br><i>This class is a singleton and cannot be created directly.</i></div><div class="hr"></div><a id="Ext.state.Manager-props"></a><h2>Public Properties</h2><div
