• Set SCT xAOD::EventInfo::Error if we get an Acts::PropagatorError::StepCountLimitReached or an Acts::CombinatorialKalmanFilterError::PropagationReachesMaxSteps.
• Add Track_PropagationError variable to NtupleDumperAlg which is true, if we have the above SCT xAOD::EventInfo::Error, otherwise false.
