// This sample uses the Place Autocomplete widget requesting only a place
// ID to allow the user to search for and locate a place. The sample
// then reverse geocodes the place ID and displays an info window
// containing the place ID and other information about the place that the
// user has selected.

// 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">
