HOW TO USE
----------

// Locally stored data
var LocalObject = Backbone.Model.extend({,
    defaults : {
        ...    
    },

    localStorage : new Store("myLocalStore")
});


// Remotely stored data
var RemoteObject = Backbone.Model.extend({,
    defaults : {
        ...    
    },

    url : "my/remote/storage/"
});


// It is also possible to have objects that are stored both, locally 
// and remote. In that case, you just have to specify where to save 
// or fetch data to/from.
var HybridObject = Backbone.Model.extend({
    defaults : {
        ...    
    },

    localStorage : new Store("myLocalStore"),

    url : "my/remote/storage/",

    fetch : function (opts) {
        opts.location = "local"; // default is remote
        Backbone.Model.prototype.fetch.apply(this, arguments);
    },

    save : function (attrs, opts) {
        opts.location = "local"; // default is remote
        Backbone.Model.prototype.save.apply(this, arguments);
    }
});

// It also works for collections.
