Detailed Description

Celeritas setup for standalone apps.

The order of initialization and loading follows the member declarations:

• System attributes (GPU activation etc.) are set first
• Problem info is loaded
• Geant4 is initialized (if not using full ROOT data)
• Geant4 data is loaded (also if not using full ROOT)
• External Geant4 data files (such as EM LOW) are loaded
• Optional control/diagnostic overrides are loaded
• Events are loaded

The input Problem can be an embedded struct or a path to a file to import.

Todo:

physics_import will be a std::optional<GeantImport> after all the ImportData is merged into Problem .
