/**
 *  Optional. A string which identifies an Autocomplete session for billing
 *  purposes. Must be a URL and filename safe base64 string with at most 36
 *  ASCII characters in length. Otherwise an INVALID_ARGUMENT error is
 *  returned.
 *  The session begins when the user starts typing a query, and concludes when
 *  they select a place and a call to Place Details or Address Validation is
 *  made. Each session can have multiple queries, followed by one Place Details
 *  or Address Validation request. The credentials used for each request within
 *  a session must belong to the same Google Cloud Console project. Once a
 *  session has concluded, the token is no longer valid; your app must generate
 *  a fresh token for each session. If the `session_token` parameter is
 *  omitted, or if you reuse a session token, the session is charged as if no
 *  session token was provided (each request is billed separately).
 *  We recommend the following guidelines:
 *  * Use session tokens for all Place Autocomplete calls.
 *  * Generate a fresh token for each session. Using a version 4 UUID is
 *    recommended.
 *  * Ensure that the credentials used for all Place Autocomplete, Place
 *    Details, and Address Validation requests within a session belong to the
 *    same Cloud Console project.
 *  * Be sure to pass a unique session token for each new session. Using the
 *    same token for more than one session will result in each request being
 *    billed individually.
