+/**
+ * @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());
+   var win = new Window(...);
+   win.restoreState();
+}
+ </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.
+ * @singleton
