// feature. People can enter geographical searches. The search box will return a
// pick list containing a mix of places and predicted search terms.
// This example requires the Places library. Include the libraries=places
// parameter when you first load the API. For example:
// <script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places">
