Further Relator enhancements

Here are two other useful Relator methods:

constructor : function (that) {
    this.set(that);
    return this.get(that); // Assign to var _ = __.constructor(this);
},
method : function (that) { // Alias for get()
    return this.get(that); // Assign to var _ = __.method(this);
},

Now we can just do this to get our private variables:

var Constructor = function () {var __ = Relator.$(); // We use two underscores here (doing it for brevity, as we may use this often)
    function Constructor (doc) {var _ = __.constructor(this); // Set up and gets private access
        // ...
    }
    Constructor.prototype = {
        constructor : Constructor,
        someMethod : function () {var _ = __.method(this); // Gets private access
            // ... 
        }
    };
    return Constructor;
})();
