Credentials object for OAuth 2.0.
Credentials can be applied to an httplib2.Http object using the authorize()
method, which then adds the OAuth 2.0 access token to each request.
OAuth2Credentials objects may be safely pickled and unpickled.

Authorize an httplib2.Http instance with these credentials.
The modified http.request method will add authentication headers to each
request and will refresh access_tokens when a 401 is received on a
request. In addition the http.request method has a credentials property,
http.request.credentials, which is the Credentials object that authorized
it.
Args:
http: An instance of httplib2.Http
or something that acts like it.
Returns:
A modified instance of http that was passed in.
Example:
h = httplib2.Http()
h = credentials.authorize(h)
You can't create a new OAuth subclass of httplib2.Authenication
because it never gets passed the absolute URI, which is needed for
signing. So instead we have to overload 'request' with a closure
that adds in the Authorization header and then calls the original
version of 'request()'.
