Demonstrates the use of Pantheios to log instances of multibyte string types in a wide string C++ program, using the pantheios::w2m inserter.

 * Purpose:     C++ example program for Pantheios. Demonstrates:
 *
 *                - use of Pantheios inserters for w2m types
 *                - use of pantheios::logputs() in bail-out conditions
