/**
* @class Ext.state.Manager
* This is the global state manager. 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>
// in your initialization function
init : function(){
Ext.state.Manager.setProvider(new Ext.state.CookieProvider());
}
</code></pre>
* This class passes on calls from components to the underlying {@link Ext.state.Provider} so that
* there is a common interface that can be used without needing to refer to a specific provider instance
* in every component.
