Class StorageDevice

StorageDevice provides three key/value stores

• Persistent: Things saved here will remain here, even after the player leaves the page. This currently uses the HTML5 persistent storage API, which has a limit of 5 MB.
• Session: Things saved here will remain as the player moves among levels, but will be discarded when the player exits/refreshes the browser.
• Level: Things saved here will remain only until the player moves to another level.

Note that Session and Level can story any data type. Persistent can only store strings, so you'll need JSON serialization for fancy stuff.
