 * \file
 * \brief C API: Plural rules, select plural keywords for numeric values.
 *
 * A UPluralRules object defines rules for mapping non-negative numeric
 * values onto a small set of keywords. Rules are constructed from a text
 * description, consisting of a series of keywords and conditions.
 * The uplrules_select function examines each condition in order and
 * returns the keyword for the first condition that matches the number.
 * If none match, the default rule(other) is returned.
 *
 * For more information, see the LDML spec, C.11 Language Plural Rules:
 * http://www.unicode.org/reports/tr35/#Language_Plural_Rules
 *
 * Keywords: ICU locale data has 6 predefined values -
 * 'zero', 'one', 'two', 'few', 'many' and 'other'. Callers need to check
 * the value of keyword returned by the uplrules_select function.
 *
 * These are based on CLDR <i>Language Plural Rules</i>. For these
 * predefined rules, see the CLDR page at
 * http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
