This object will be owned by libaddressinput, so there's no need to instantiate
it here. The interface will be:

  AddressValidation(Downloader*, Storage*)

You would instantiate it with:

  AddressValidation validation(new ValidationDownloader(context),
                               new ValidationStorage(context)).
