 * This example demonstrates adding tracks, removing tracks, and replacing tracks in a playlist. At this time of writing this

 * documented here: https://developer.spotify.com/spotify-web-api/authorization-guide/#authorization_code_flow
 *
 * Codes are given for a set of scopes. For this example, the scopes are playlist-modify-public.
 * Scopes are documented here:
 * https://developer.spotify.com/spotify-web-api/using-scopes/
