add needed parameters to the simulation object that include cosmology parameters in order to perform certain calculations as live calculations and not require loading in a snapshot. This includes Hubble0, Omega0. Lambda, dMsolUnit, dKpcUnit (the latter are for converting Hubble0 from simulation units)
