Format of the text file obtained from the redshift distribution. #228
Description
Many formats are possible to store the redshift distribution in the tomographic case, e.g., the non-tomographic redshift distribution sums to one vs all the tomographic bin redshift distribution individually sum up to one.
It will be important to assess if this matters in CosmologyValidation. For theory computations it should not as CAMB performs a normalisation.

I believe that any (tomographic or not) individual redshift distribution needs to be normalised, \int n(z) dz = 1. Best to do this in the code to ensure this normalisation.
