// GEANT 4 class header file
//
// G4ofstreamDestination.hh
// Sends G4cout and G4cerr to a file.
//
// To send G4cout to a file instantiate an instance of
//     G4CoutToFile
// To send G4cerr to a file use instead
//     G4CerrToFile
//
// Example:
//  #include "G4ofstreamDestination.hh"
//  #include "G4ios.hh"
//  int main(int,char**) {
//      G4UImanager::GetUIpointer();
//      G4iosInitialization();
//      G4CoutToFile myout("MyOut_out.log"); // G4cout to file
//      G4CerrToFile myout("MyOut_err.log"); // G4cerr to file
