[FLASH-USERS] parameters changes allowed on restart?

Okay, I managed to get the integration step size to begin auto changing
again by replacing the code in
source/physics/Hydro/HydroMain/split/MHD_8WV/Hydro_init.F90
that says:
if (.not.dr_restart) then
hy_dtmin = HUGE(hy_dtmin)
else
hy_dtmin = dr_dt
endif
with just:
hy_dtmin = HUGE(hy_dtmin)
That is, with my combination of units, I think the driver is not
properly setting dr_dt on restarts - I'll leave it to the experts to
decide how this should really be fixed...
Thanks,
Andy S.
