/**
 * CultureInfo class.
 *
 * Represents information about a specific culture including the
 * names of the culture, the calendar used, as well as access to
 * culture-specific objects that provide methods for common operations,
 * such as formatting dates, numbers, and currency.
 *
 * The CultureInfo class holds culture-specific information, such as the
 * associated language, sublanguage, country/region, calendar, and cultural
 * conventions. This class also provides access to culture-specific
 * instances of DateTimeFormatInfo and NumberFormatInfo. These objects
 * contain the information required for culture-specific operations,
 * such as formatting dates, numbers and currency.
 *
 * The culture names follow the format "<languagecode>_<country/regioncode>",
 * where <languagecode> is a lowercase two-letter code derived from ISO 639
 * codes. You can find a full list of the ISO-639 codes at
 * http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt
 *
 * The <country/regioncode2> is an uppercase two-letter code derived from
 * ISO 3166. A copy of ISO-3166 can be found at
 * http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html
 *
 * For example, Australian English is "en_AU".
