Setting class behaves as singleton object, gets its values dynamically, then can be read and written to directly with the setting (in this case 'key1' , 'key2' , and 'key3' ) but can still offer other attributes if desired, ie pass :description as the second param, and you get the description. Otherwise always behaves as value.
