Provides functionality to nest controllers/resources. If a controller is nested, the parent classes and namespaces may be defined as an array in the :nesting class attribute. For example, a cities controller, nested in country and a admin namespace, may define this attribute as follows:
self.nesting = :admin, Country
Adds the :nesting class attribute and parent helper methods to the including controller.
