std::optional< GeantSetup >	geant_setup
	Set up Geant4 (if all the data isn't already loaded into Problem)

Detailed Description

Celeritas setup for standalone apps.

The order of initialization and loading (see celeritas::setup::Problem ) 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:

Replace problem with a variant (either problem or file to load from)?

Note

geant_setup is always required for real problems

Todo:

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

Add PhysicsFromGeantFiles after physics_import

Add an option to override control/diagnostics?
