Pull all users from Box and write the box user count and user list into a Google Spreadsheet. The spreadsheet must have two sheets. One sheet must be called 'User Summary' and the other sheet must be called 'User List'. The Script is designed to be run nightly so that a user count over time can be kept as well as a current user list. See https://developer.box.com/v2.0/docs/authentication-with-jwt for specifics on how Box JWT authentication works.
