also use on browser

On browser, storages will attached to window automatically.
Now, almost all browsers have implemented web-storage, so that
native module is used in natural.

If you want to use this storages on a modern browser,
you have to prepare "module.exports" object or "global" object
on window namespace.

Ways to import module with using "require-js"
or "foonyah" is awesome way for importing module.

And more, 4 functions to access "document.cookie" are attached to exports.
docCookie(document) ... change cookie document to arguments0 provided.
keyCookie() ... get cookies key array.
setCookie(key, value, options) ... set a cookie value. options accepts or to given days of period.
getCookie(key) .. get a cookie value.

    foonyah.require(src).done(function(){
      localStorage.setItem( ... )
    });
