Demonstrates the use of Pantheios to log the current host identity in a C++ program, using the pantheios::hostId inserter.

 * File:        examples/cpp/inserters/example.cpp.inserter.hostid/example.cpp.inserter.hostid.cpp
 *
 * Purpose:     C++ example program for Pantheios. Demonstrates:
 *
 *                - use of Pantheios inserter for host ids
 *                - use of pantheios::logputs() in bail-out conditions
