// Load the integration of a third-party analytics API such as Google Analytics.
// Since we cannot guarantee the quality of the third-party service (e.g. their
// server may take noticeably long time to respond), it is in our best interest
// (in the sense that the intergration of the analytics API is important to us
// but not enough to allow it to prevent people from joining a conference) to
// download the API asynchronously. Additionally, Google Analytics will download
// its implementation asynchronously anyway so it makes sense to append the
// loading on our side rather than prepend it.
