// CounterMgr.h: interface for the CCounterMgr classes.
//
// MODULE: COUNTERMGR.H
//
// PUTPOSE: Global pool of pointers to status counters
//      These pointers can be accessed through name (string, like "Topic imsetup"
//		or "Thread 1") and counted event identifier (long).
//		There is only one instance of this class in the programm.
//      Manipulation with members of this class should be thread safe.
