/**
 * 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. GOTO Step 3
