/**
* 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);
*

* @cfg {String} path
* The path for which the cookie is active. Defaults to root '/' which makes it active for all pages in the site.
*/
/**
* @cfg {Date} expires
* The cookie expiration date. Defaults to 7 days from now.
*/
/**
* @cfg {String} domain
* The domain to save the cookie for. Note that you cannot specify a different domain than your page is on, but you can
* specify a sub-domain, or simply the domain itself like 'sencha.com' to include all sub-domains if you need to access
* cookies across different sub-domains. Defaults to null which uses the same domain the page is running on including
* the 'www' like 'www.sencha.com'.
