// This class enables measuring the CPU time between two points of code
// execution, regardless of the scope of these points of code. A meter is
// identified by its name (string of chars). So multiple objects in various
// places of user code may point to the same meter. The results will be
// printed on stdout upon finish of the program. For details see
// OSD_PerfMeter.h
