[Halld-offline] Bug (in hdgeant?) in how DMCThrown's are setup

[Paul Mattione]

I've encountered a problem with how particles that are decayed in hdgeant point to their parent particles.  I generated a K0 and let hdgeant decay it, but if the resulting pions also decay then their decay products (e.g. muons, gammas, etc.) do not accurately indicate what the parent particle is.  They show that the parent particle is the K0 rather than one of the pions.  Could someone more familiar with hdgeant (and how it's outputted to hddm) please fix this?  Thanks!
