+/**
+ * Ensure that a user is logged in before proceeding to next route middleware.
+ *
+ * This middleware ensures that a user is logged in.  If a request is received
+ * that is unauthenticated, the request will be redirected to a login page (by
+ * default to `/login`).
+ *
+ * Additionally, `returnTo` will be be set in the session to the URL of the
+ * current request.  After authentication, this value can be used to redirect
+ * the user to the page that was originally requested.
+ *
+ * Options:
+ *   - `redirectTo`   URL to redirect to for login, defaults to _/login_
+ *   - `setReturnTo`  set redirectTo in session, defaults to _true_
+ *
+ * Examples:
+ *
+ *     app.get('/profile',
+ *       ensureLoggedIn(),
+ *       function(req, res) { ... });
+ *
+ *     app.get('/profile',
+ *       ensureLoggedIn('/signin'),
+ *       function(req, res) { ... });
+ *
+ *     app.get('/profile',
+ *       ensureLoggedIn({ redirectTo: '/session/new', setReturnTo: false }),
+ *       function(req, res) { ... });
+ *
+ * @param {Object} options
+ * @return {Function}
+ * @api public
