#display_name(resource) ⇒ Object
Attempts to call any known display name methods on the resource. See the setting in ‘application.rb` for the list of methods and their priority.

#display_name_method_for(resource) ⇒ Object
Looks up and caches the first available display name method. To prevent conflicts, we exclude any methods that happen to be associations. If no methods are available and we’re about to use the Kernel’s ‘to_s`, provide our own.
