function TimeStamperCLS() {
//  Author:     Branimir Petrovic
//  Date:       9 January 2002
//  Version:    1.1.0
//
//  Revision History:
//      9 January 2002      V 1.0.0
//      13 January  2002    V 1.1.0     Added getVersion() method
//
//
//  This class is used to produce prefix or suffix to be appended
//  before or after file name (for one of many situations where files
//  differ only by a date and time stamp embedded in the file name).
//
//  Methods:
//      - getClassName()
//      - getVersion()              //  Returns version string "1.1.0"
//      - getNow([oDate])
//      - getYYYYMMDD([oDate])
//      - getHHMMSS([oDate])
//      - getFullAsPostfix([oDate])
//      - getFullAsPrefix([oDate])
//
//  Note:
//      All methods accept object of type Date in which case time stamps
//      are based on this object's value. If methods are called without
//      any param, then each call will create new Date object and return
//      its "stringified" value.
