* let the developer define the rules himself, instead of potentially break applications if we change rules in the
* future.
*
* However, you can find most of the up-to-date plural rules for most languages in those links:
* - http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
