/**
 * Creates an instance of `Strategy`.
 *
 * The anonymous authentication strategy passes authentication without verifying
 * credentials.
 *
 * Applications typically use this as a fallback on endpoints that can respond
 * to both authenticated and unauthenticated requests.  If credentials are not
 * supplied, this stategy passes authentication while leaving `req.user` set to
 * `undefined`, allowing the route to handle unauthenticated requests as
 * desired.
 *
 * Examples:
 *
 *     passport.use(new AnonymousStrategy());
 *
 * @constructor
 * @api public
