Description:

Stubs out a scaffolded controller and its views. Different from rails
scaffold_controller, it uses strong_parameters via action_permission
to whitelist permissible attributes in a private method.
Pass the model name, either CamelCased or under_scored, the parameters
and optionally the controller instance (otherwise, the controller
name is retrieved as a pluralized version of the model name)

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

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