/**
 * `Strategy` constructor.
 *
 * The example-oauth2orize authentication strategy authenticates requests by delegating to
 * example-oauth2orize using the OAuth 2.0 protocol.
 *
 * Applications must supply a `verify` callback which accepts an `accessToken`,
 * `refreshToken` and service-specific `profile`, and then calls the `done`
 * callback supplying a `user`, which should be set to `false` if the
 * credentials are not valid.  If an exception occured, `err` should be set.
 *
 * Options:
 *   - `clientID`      your example-oauth2orize application's client id
 *   - `clientSecret`  your example-oauth2orize application's client secret
 *   - `callbackURL`   URL to which example-oauth2orize will redirect the user after granting authorization
 *
 * Examples:
 *
 *     passport.use(new Thirty7SignalsStrategy({
 *         clientID: '123-456-789',
 *         clientSecret: 'shhh-its-a-secret'
 *         callbackURL: 'https://www.example.net/auth/example-oauth2orize/callback'
 *       },
 *       function(accessToken, refreshToken, profile, done) {
 *         User.findOrCreate(..., function (err, user) {
 *           done(err, user);
 *         });
 *       }
 *     ));

 * @param {Function} verify
