Subject: [PATCH] Add devise gem and a first test for user login

Devise is a commonly used gem for user authentication and management. Using
rails generators and Devise allows us to get a lot of boilerplate code for
user authentication and management and means we don't have to revinvent the
wheel. Styling will need to be done for the necessary pages and there are
likely to be bits of generated code that can be deleted. This will act as
a starting point to be built up from using TDD.

+
+  # ==> Configuration for :encryptable
+  # Allow you to use another hashing or encryption algorithm besides bcrypt (default).
+  # You can use :sha1, :sha512 or algorithms from others authentication tools as
+  # :clearance_sha1, :authlogic_sha512 (then you should set stretches above to 20
+  # for default behavior) and :restful_authentication_sha1 (then you should set

+  #
+  # Require the `devise-encryptable` gem when using anything other than bcrypt
+  # config.encryptor = :sha512
+
+  # ==> Scopes configuration
+  # Turn scoped views on. Before rendering "sessions/new", it will first check for
+  # "users/sessions/new". It's turned off by default because it's slower if you
+  # are using only default views.
+  # config.scoped_views = false

+  # only the current scope. By default, Devise signs out all scopes.
+  # config.sign_out_all_scopes = true
+
+  # ==> Navigation configuration
+  # Lists the formats that should be treated as navigational. Formats like
+  # :html, should redirect to the sign in page when the user does not have
+  # access, but formats like :xml or :json, should return 401.

+  # up on your models and hooks.

+
+  # ==> Warden configuration
+  # If you want to use other strategies, that are not supported by Devise, or
+  # change the failure app, you can configure them inside the config.warden block.
+  #
+  # config.warden do |manager|
+  #   manager.intercept_401 = false
+  #   manager.default_strategies(scope: :user).unshift :some_external_strategy
+  # end
+
+  # ==> Mountable engine configurations
+  # When using Devise inside an engine, let's call it `MyEngine`, and this engine
+  # is mountable, there are some extra configurations to be taken into account.
+  # The following options are available, assuming the engine is mounted as:
+  #
+  #     mount MyEngine, at: '/my_engine'
+  #
+  # The router that invoked `devise_for`, in the example above, would be:
+  # config.router_name = :my_engine
+  #
+  # When using OmniAuth, Devise cannot automatically set OmniAuth path,
+  # so you need to do it manually. For the users scope, it would be:
+  # config.omniauth_path_prefix = '/my_engine/users/auth'
+
+  # ==> Turbolinks configuration
+  # If your app is using Turbolinks, Turbolinks::Controller needs to be included to make redirection work correctly:
+  #
+  # ActiveSupport.on_load(:devise_failure_app) do
+  #   include Turbolinks::Controller
+  # end
+
+  # ==> Configuration for :registerable
+
+  # When set to false, does not sign a user in automatically after their password is
+  # changed. Defaults to true, so a user is signed in automatically after changing a password.
+  # config.sign_in_after_change_password = true
