  Description: 
               A helper class to convert integer literals between decimals, 
               octals, Binaries and hexadecimals.
               
  Revision: 
    - Veriosn 1.0, 2005-05-13, first release
    - Version 1.1, 2009-08-17, fixed an overflow bug with long type,  use size_t instead.
