Expirable Localstorage

Once upon a time, localstorage never get expired. But this time, everything has changed except your coding habit. All you need to do is include the expirable-localstorage.js into your web page, and localstorage becomes expirable.

Before: localStorage.setItem('weather_today','Sunny');

Now: localStorage.setItem('weather_today','Sunny',{expires:'1d'});

As the code above indicated, the 3rd argument is extended into native setItem method. You can pass-in the expiration configration and everything will be done in the background.
