23 * ===========================================================================

25 * Created on: Sept 2nd, 2001
26 *
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.
