Authentication route is not displaying in feathers swagger

[justraman]

After using this library, the docs have only model routes, authentication route is completely invisible.

app.configure(sequelize);



// Configure other middleware (see `middleware/index.js`)
app.configure(middleware);
app.configure(authentication);



app.configure(sequelizeToJsonSchemas as any);

app.configure(
    swagger({

// Set up our services (see `services/index.js`)

// Set up event channels (see channels.js)
