Detailed Description

Small wrapper class for easy manipulation with generic counters and IStatSvc&ICounterSvc interface.

It acts as "smart pointer" fro StatEntity objects, and allows manipulation with StatEntity objects, owned by GaudiCommon<TYPE> base class and/or IStatSvc/ICounterSvc

   long nTracks = ... ;
   Stat stat( chronoSvc() , "#tracks" , nTracks ) ;

Alternatively one can use operator methods:

   long nTracks = ... ;
   Stat stat( chronoSvc() , "#tracks" ) ;
   stat += nTracks ;
