/**
 * Default implementation of plural rules.  The i18n generator will
 * substitute subclasses of this class, which may reside anywhere in
 * the package hierarchy, based on the locale.  See Localizable
 * for more details on this process.
 * 
 * The default implementation here always selects the default form.
 * 
 * To define a new language, simply declare a subclass of this class
 * that is named with the locale you want to specify, such as
 * DefaultRule_en_uk for English spoken in the UK (note the lower-cased
 * tag).
 * 
 * This is an implementation of the language pluralization rules described
 * at http://translate.sourceforge.net/wiki/l10n/pluralforms
 * 
 * Eventually, all these rules will be machine generated from Unicode's
 * CLDR, perhaps with some additional data that isn't kept there if
 * necessary.  The current subclasses are defined just to get reasonable
 * plural support for most of the common languages -- in particular, you
 * should not rely on particular keywords for the plural forms of a
 * given language.
