This is based on the Token2.0 class provided in httr. These objects should be created through the constructor function gargle2.0_token(). In the base Token2.0 class, tokens are cached based on endpoint, app, and scopes. For the Gargle2.0 subclass, the identifier or key is expanded to include the email address associated with the token. This makes it easier to work with Google APIs with multiple identities. The default location for the token cache is also different: it's now "~/.R/gargle/gargle-oauth" instead of ./.httr-oauth.



An R6 class object.
