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);
});
</script>
