Spine indexeddb is a simple api to provide persistence using the indexeddb. For usage just make any model extend the Spine.Model.IndexedDb module. As followed:

User = Spine.Model.sub();
User.configure('User','name','age','email');
User.extend(Spine.Model.IndexedDb);

By default, it will create a connection called default and an objectStore with the same name like the model name, in the previous example will be called User. To change the default just configure the User.dbMetadata object.
