//     Timeline: The GitHub global public timeline
//     User: The public timeline for any user, using URI template

//     Current user: The private timeline for the authenticated user

//         authenticated user
//     Current user organizations: The private timeline for the organizations
//         the authenticated user is a member of.
//
// Note: Private feeds are only returned when authenticating via Basic Auth
// since current feed URIs use the older, non revocable auth tokens.
