[G12] GSIM and eloss

[Cole Smith]

Not sure what you mean by 'breaks' but if you set LOSS 0
all charged particles will just multiple scatter forever and never
stop until some data structure that stores the track steps
gets filled up and overflows.

Maybe you want to use geantinos, which are massless
chargeless particles sensitive only to geometry used for
debugging where a particle is.  Geantinos have particle
type 48.
