//events - a super-basic Javascript (publish subscribe) pattern

class Event{
    constructor(){
        this.events = {};
    }

    on(eventName, fn) {
        this.events[eventName] = this.events[eventName] || [];
        this.events[eventName].push(fn);
    }

    off(eventName, fn) {
        if (this.events[eventName]) {
            for (var i = 0; i < this.events[eventName].length; i++) {
                if (this.events[eventName][i] === fn) {
                    this.events[eventName].splice(i, 1);
                    break;
                }
            };
        }
    }

    trigger(eventName, data) {
