//This is a very simple example to show the sequence required to call the stream() function
//
//A much more complicated version of this app is streaming.js which handles continuous long polling
//for data, expiring tokens, automatically wakes up the car when needed, handles sleep mode properly,
//and writes the data to either a file or a mongodb database.
//
//First you need to call vehicles() to get the vehicle_id and tokens to use as passwords
//Note that the password used for the REST call to vehicles() is different than
//   the password used in the streaming API call to stream() even though the email is the same
