Description:
    Replaces the Rails default controller generator with a cleaner, controller. Includes non-template actions, authentication, and SLIM templates

Example:
    rails generate controller users new create show index --authenticate admin

    This will create:
      app/controllers/users_controller.rb
      app/views/users/new.html.slim
      app/views/users/show.html.slim
      app/views/users/index.html.slim
