+*  To enable logging (either with RDebug or RFileLogger) follow steps below:
+*  1. Create folder c:\Logs\VT
+*  2. Create file VTLOGCONF.txt
+*  3. Open the file and define logging level by hexadecimal digit, 
+*     see TLogLevel in class declaration below. Example: 2007 means that
+*     constructors (0x1), destructors (0x2 ) in media subsystem (0x4) are 
+*     logged to file (0x2000), i.e. the values are bitwise or'ed. Log file
+*     name is "<thread name>.txt" where <thread name> is name of the thread
