Tries to find a controller for the given ActiveRecord
model. Searches in the namespace of the current controller for singular and plural versions of the conventional “#{model}Controller” syntax. You may override this method to customize the search routine.

Create the automatic column links. Note that this has to happen when configuration is done, because otherwise the Nested module could be disabled. Actually, it could still be disabled later, couldn’t it?
