Check if google maps API has already been loaded

Firstly, it's nice that markerWithLabel is now available as a bower package - kudos for that.

There is an issue though that happens when google maps API has already been loaded before markerWithLabel module is required.

You have included the Google Maps API multiple times on this page. This may cause unexpected errors.

A check whether google maps API has already been included would be nice e.g.

(function(factory) {
    if (typeof define === 'function' && define.amd) {
        // AMD
        if (!window.google) {
          define(['async!https://maps.googleapis.com/maps/api/js?key=AIzaSyD1O9N-77QOCYJ6wgsbJWgJYBJWd3K_VJg&sensor=false'], factory);
        }

Hi @svenlaater ! I'll try to figure out a nice way to add this and update the code. Thanks a lot for your suggestion.
