 * Creates a RuleBasedNumberFormat from a predefined description.  The selector

 * @param locale The locale for the formatter.
 * @param format A selector code specifying which kind of formatter to create for that
 * locale.  There are four legal values: SPELLOUT, which creates a formatter that
 * spells out a value in words in the desired language, ORDINAL, which attaches
 * an ordinal suffix from the desired language to the end of a number (e.g. "123rd"),
 * DURATION, which formats a duration in seconds as hours, minutes, and seconds, and
 * NUMBERING_SYSTEM, which is used to invoke rules for alternate numbering
 * systems such as the Hebrew numbering system, or for Roman numerals, etc..
