/**
* An internal data warehouse for information (locale elements) needed to
* implement locale dependent formatting for the standard set of locales
* The current implementation utilizes a class LocaleElements which is
* created from plain text source file(s) by a small compiler (LocaleTool)
*
* Example of use:
* <pre>
* Locale desiredLocale = new Locale("DA","DK","");
* ResourceBundle resource = ResourceBundle.load("java.util.LocaleElements",
* desiredLocale);
* // Pass one of the following:
* "LocaleString", // locale id based on iso codes
* "LocaleID", // Windows id
* "ShortLanguage", // iso-3 abbrev lang name
* "ShortCountry", // iso-3 abbrev country name
* "Languages", // language names
* "Countries", // country names
* "MonthNames", // ARRAY january
* "MonthAbbreviations", // ARRAY abb january
* "DayNames", // ARRAY Monday
* "DayAbbreviations", // ARRAY abb Monday
* "AmPmMarkers", // ARRAY am marker
* "Eras", // era strings
* "NumberPatterns", // ARRAY decimal pattern
* "CurrencyElements", // ARRAY local currency symbol
* "DateTimePatterns", // ARRAY full time pattern
* "DateTimeElements", // ARRAY first day of week
* "CollationElements", // collation order
*
* String myString string = resource.getString(LocaleString);
* // or
* String[] myStrings strings = resource.getStringArray(LocaleString);
* </pre>
