Detailed Description

Redirect the given stream to an internal stringstream.

This is primarily for interfacing with poorly-behaved external libraries that write to cout/cerr by default.

ScopedStreamRedirect silenced(&std::cout);
LoadVecGeom();
CELER_LOG(diagnostic) << "Vecgeom said: " << silenced.str();

The environment variable CELER_DISABLE_REDIRECT will prevent stream redirection, which might be needed if the code segfaults/aborts before this class's destructor is reached.
