-/**
- * Defines rules for mapping positive long values onto a small set of
- * keywords. Rules are constructed from a text description, consisting
- * of a series of keywords and conditions. The {@link #select} method
- * examines each condition in order and returns the keyword for the
- * first condition that matches the number. If none match,
- * default rule(other) is returned.
- *
- * Examples:<pre>
- * "one: n is 1; few: n in 2..4"</pre>
- * This defines two rules, for 'one' and 'few'. The condition for
- * 'one' is "n is 1" which means that the number must be equal to
- * 1 for this condition to pass. The condition for 'few' is
- * "n in 2..4" which means that the number must be between 2 and
- * 4 inclusive for this condition to pass. All other numbers
- * are assigned the keyword "other" by the default rule.
- * </p><pre>
- * "zero: n is 0; one: n is 1; zero: n mod 100 in 1..19"</pre>
- * This illustrates that the same keyword can be defined multiple times.
- * Each rule is examined in order, and the first keyword whose condition
- * passes is the one returned. Also notes that a modulus is applied
- * to n in the last rule. Thus its condition holds for 119, 219, 319...
- * </p><pre>
- * "one: n is 1; few: n mod 10 in 2..4 and n mod 100 not in 12..14"</pre>
- * This illustrates conjunction and negation. The condition for 'few'
- * has two parts, both of which must be met: "n mod 10 in 2..4" and
- * "n mod 100 not in 12..14". The first part applies a modulus to n
- * before the test as in the previous example. The second part applies
- * a different modulus and also uses negation, thus it matches all
- * numbers _not_ in 12, 13, 14, 112, 113, 114, 212, 213, 214...
- * </p>
- * <p>
- * Syntax:<pre>
- * \code
- * rules = rule (';' rule)*
- * rule = keyword ':' condition
- * keyword = <identifier>
- * condition = and_condition ('or' and_condition)*
- * and_condition = relation ('and' relation)*
- * relation = is_relation | in_relation | within_relation | 'n' <EOL>
- * is_relation = expr 'is' ('not')? value
- * in_relation = expr ('not')? 'in' range
- * within_relation = expr ('not')? 'within' range
- * expr = 'n' ('mod' value)?
- * value = digit+
- * digit = 0|1|2|3|4|5|6|7|8|9
- * range = value'..'value
- * \endcode
- * </pre></p>
- * <p>
- * The difference between 'in' and 'within' is that 'in' only includes
- * integers in the specified range, while 'within' includes all values.</p>
- * <p>
- * Keywords
- * could be defined by users or from ICU locale data. There are 6
- * predefined values in ICU - 'zero', 'one', 'two', 'few', 'many' and
- * 'other'. Callers need to check the value of keyword returned by
- * {@link #select} method.
- * </p>
- *
- * Examples:<pre>
- * UnicodeString keyword = pl->select(number);
- * if (keyword== UnicodeString("one") {
- * ...
- * }
- * else if ( ... )
- * </pre>
- * <strong>Note:</strong><br>
- * <p>
- * ICU defines plural rules for many locales based on CLDR <i>Language Plural Rules</i>.
- * For these predefined rules, see CLDR page at
- * http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
- * </p>
