/**  * This function retrieves the current script user's uploaded videos. To execute,  * it requires the OAuth read/write scope for YouTube as well as user authorization.  * In Apps Script's runtime environment, the first time a user runs a script, Apps  * Script will prompt the user for permission to access the services called by the  * script. After permissions are granted, they are cached for some periodF of time.  * The user running the script will be prompted for permission again once the  * permissions required change, or when they are invalidated by the  * ScriptApp.invalidateAuth() function.  *  * This script takes the following steps to retrieve the active user's uploaded videos:  *    1. Fetches the user's channels  *    2. Fetches the user's 'uploads' playlist  *    3. Iterates through this playlist and logs the video IDs and titles  *    4. Fetches a next page token (if any). If there is one, fetches the next page.
