Detailed Description

MsgStreamTC class to be used in TrigConf equivalent to Gaudi's MsgStream.

The usage and behavior is identical to the default Gaudi message stream. If the code is run within a Gaudi/Athena environment, the MsgStreamTC will try to print its messages via the Gaudi MessageSvc. This is achieved via weak linking. In a non-Gaudi/Athena environment std::cout will be used. The class can be used directly or better via inheriting from TrigConf::TrigConfMessaging, which is the equivalent of AthMessaging.

Main difference to Gaudi MsgStream:

• OutputLevel cannot be configued via job options, instead the global OutputLevel of the MessageSvc is being used
