/*! Easily define singular and plural forms.
 *  - The key with "(0)" appended is used if n == 0
 *  - The key with "(1)" appended is used if n == 1 (singular form)
 *  - The key is used unchanged in any other case (like when n>1, plural form)
 *
 * Example of a Localized.strings file content:
 *   "apple(0)" = "%2$@ n'a aucune pomme";
 *   "apple(1)" = "%2$@ n'a qu'une seule pomme";
 *   "apple"    = "%2$@ a %1$d pommes";
 * Usage: _Tf_n(@"apple", nbApples, firstName);
