</span> * A Provider implementation which saves and retrieves state via cookies. The CookieProvider supports the usual cookie
* options, such as:
*
* - {@link #path}
* - {@link #expires}
* - {@link #domain}
* - {@link #secure}
*
* Example:
*
* var cp = Ext.create('Ext.state.CookieProvider', {
* path: "/cgi-bin/",
* expires: new Date(new Date().getTime()+(1000*60*60*24*30)), //30 days
* domain: "sencha.com"
* });
*
* Ext.state.Manager.setProvider(cp);
*
