Detailed Description

Simple interface for G4VTrackingManager-based integration.

This singleton integrates both thread-local and global data with the user application. To use this class in your Geant4 application to offload tracks to Celeritas:

• Add the FastSimulationModel to regions of interest.
• Use SetOptions to set up options before G4RunManager::Initialize: usually in main for simple applications.
• Call Build and BuildForMaster from UserActionInitialization
• Call BeginOfRunAction and EndOfRunAction from UserRunAction

The CELER_DISABLE environment variable, if set and non-empty, will disable offloading so that Celeritas will not be built nor kill tracks.

The method names correspond to methods in Geant4 User Actions and must be called from all threads, both worker and master.
