Description:

Stubs out a new controller and its views. Pass the controller name, either
CamelCased or under_scored, and a list of views as arguments.

To create a controller within a module, specify the controller name as a
path like 'parent_module/controller_name'.

This generates a controller class in app/controllers and invokes helper,
template engine, assets, and test framework generators.

Example:

`quails generate controller CreditCards open debit credit close`

CreditCards controller with URLs like /credit_cards/debit.
    Controller: app/controllers/credit_cards_controller.rb
    Test:       test/controllers/credit_cards_controller_test.rb
    Views:      app/views/credit_cards/debit.html.erb [...]
    Helper:     app/helpers/credit_cards_helper.rb
