Detailed Description

This class is intended for debugging of multithreaded simulation when the amount of output is moderate to large. Output of Geant4 in each thread is forwarded to a thread-specific file. Compared to using MessageLogger, this way the synchronization is avoided. Thread safety is ensured by

• each thread gets its own file name
• each thread gets its own std::ofstream object (as RunManagerMTWorker creates a CustomUIsessionToFile object separately for each thread).
