    27:  *  Modified on: April 1st, 2002
    28:  *
    29:  *             - Added translateML() which takes data markup format,
    30:  *               and modifies name and value.
    31:  *             - Added info_ml(), changed info() to info_nv().
    32:  *             - Added a constructor which takes a string in markup format.
    33:  *             - Overloaded insertion and extraction operators to convert
    34:  *               data between pairs and maarkup like a stream call.
    35:  *             - Made getName() and getValue() as const methods.
    36:  *
    37:  *  ===========================================================================
    38:  *
    39:  *  Remark:
    40:  *
    41:  *  This is the class implementaion for CFdataPair, a class which provides
    42:  *  methods and data members for storing pairs of data.
