NAME
Cosmology_getOldRedshift
SYNOPSIS
Cosmology_getOldRedshift( real(OUT) :: zOld )
ARGUMENTS
zOld -- The simulation's last cosmological redshift
DESCRIPTION
This routine returns the cosmological redshift of the last step based upon the current cosmological scale factor based on the equation: z = 1+(1/s) where 'z' is the last cosmolgical redshift, and 's' is the last scaling factor.
