Vimeo Example

I noticed it was hard to integrate Vimeo without an example to work from so I added one. I tried to make it match the other examples as much as possible. Vimeo does not seem to have an anonymous user, so I created a dummy Vimeo app and left those credentials in the example with a note that the user should add in their own API key/secret.
