/**
 * Date Formatter class - locale-dependent formatting/parsing of dates using pattern strings and/or canned patterns.
 *
 * This class represents the ICU date formatting functionality. It allows users to
 * display dates in a localized format or to parse strings 
 * into PHP date values using pattern strings and/or canned patterns.
 * 
 * Example:
 * <code>
 * $datefmt = new DateFormatter("de-DE", LONG, SHORT, date_default_timezone_get());
 * echo $formatter->format(time());
 * </code>
 *
 * <code>
 *  $datefmt = new DateFormatter("de-DE", LONG, SHORT, date_default_timezone_get() , GREGORIAN , "yyyy-MM-dd HH:mm:ss z");
 *  echo $formatter->format(time());
 * </code>
