YouTube Video Upload Swift OAuth2

// I __think__ this actually does work, I was just providing an inavlid token.
// I've now used the upload-video.py script below that generates a token in the folder you run the script (as long as you've got credentials setup in that directory) 
// Using that token, this script works. Now I just need to figure out how to add the name, description, tags, etc.
