Unable to simulate supernova backgrounds

[guigoruiz1]

I am not sure whether it is a problem with Geant4 4.11 or the changes implemented in version 3.0.0, but I am unable to run simulations which use particle_type SUPERNOVA. The supernova class is initialised before the ConfigManager has the correct values from the macro. This causes the number of isotopes to simulate to be 0 when entering the loop.

Here is a macro for testing:

# set verbosity
/control/verbose 1
/run/verbose 1
/tracking/verbose 0

# configure supernova
/inputs/particle_type SUPERNOVA

# output path
/inputs/output_file ./output/radiogenic_Ar42_background.root

# initialize run
/run/initialize
/random/setSeeds 137 100

# event ID offset
/event/offset 0

# Supernova configs
/supernova/Event_Window 10 s
/supernova/Event_Cutoff 10 s

/supernova/N_Ar42_Decays 1

# run
/run/beamOn 10

@guigoruiz1 I have not had a chance to look at the code itself yet, but I do have a suggestion. I notice that you're doing your /supernova/... configurations after /run/initialize. Generally, runManager->Initialize() assumes that any kind of user configuration has been completed. I still have to go through the code to see if I'm correct in general, but you could test this quickly and see if we just need the documentation updated.

@kelseymh I have tried that but unfortunately it doesn't work.
