## Detailed Description

It is a simple guard, which "locks" the scope for the Auditor Service is am exception-safe way.

The pattern ensures that "post-action" will be always executed

      StatusCode Algorithm::sysInitialize ()
       {
          AuditorGuard auditor ( this ,
            auditSvc()                ,
            IAuditor::Initialize      ) ;
          ...
          StatusCode sc = ... ;
          ...
          return sc ;
       }

      StatusCode Algorithm::sysExecute ()
       {
          AuditorGuard auditor ( this       ,
            auditSvc()                      ,
            IAuditor::execute               ) ;
          ...
          StatusCode sc = ... ;
