  Dynamically loads Google JavaScript API `gapi`, firing the `js-api-load` event when ready.
  
  Any number of components can use `<google-js-api>` elements, and the library will only be loaded once.
  
  ##### Example
  
      <google-js-api></google-js-api>
      <script>
        var api = document.querySelector('google-js-api');
        api.addEventListener('js-api-load', function(e) {
          console.log('API loaded', gapi);
        });
