[Halld-offline] control of decay modes in hdgeant

[Kei Moriya]

Hi,

I had a question regarding the decay modes in hdgeant.
I would like to have control over how my particles decay,
so that I don't waste 1/3 of my CPU on events that do not
have the topology I want.

Is there a way to edit some file and specify what the decay
modes for a given particle should be? I looked around and it
seems like I need to edit something to do with the function
gsdk, but can't find any non-executables with it in the repository.

Does anybody have any ideas?
Thanks,
	Kei
