Filename          : TTMStatistics.h
Author            : Rene Wilhelm
Date              : 28-06-2001
Description       : TTM Statistics class definition
Language Version  : C++
OSs Tested        : Solaris 2.6, Solaris 8, Debian Linux 2.2

TTMStatistics objects store the TTM statistics of measurements
between specific source and destination box.  

While processing TTM data files, the user adds information by calling
the Update() method. Once finished reading files, the summary 
numbers can be retrieved with corresponding methods.
