This small module was written for CosmoSIS.

Supernova type IA measurements are a standard(izable) candle 
that can be used to probe the relation between luminosity distance 
and redshift.  At low redshifts this directly probes the Hubble parameter,
H0.

The Riess et al 3% solution measurement of H0 is used in this module.
