/*
    A basic implementation of the Publisher/Subscriber design pattern.
    Developed by @addyosmani and @integralist

    Example Usage:

                    // Create subscriber function to be called when topic publishes an event
                    var testSubscriber = function (topics, data) {
                        console.log(topics + ': ' + data);
                    };
