A concurrent parallel processor to help in running several async functions.

var stack = new Y.Parallel();

                            for (var i = 0; i < 15; i++) {
                                Y.io('./api/json/' + i, {
                                    on: {
                                        success: stack.add(function() {
                                            Y.log('Done!');
                                        })
                                    }
                                });
                            }

                            stack.done(function() {
                                Y.log('All IO requests complete!');
