Subject: Pipeline now downloads and uses an input dataset

In most analysis situations (except for simulations), an input dataset is
necessary, but that part of the pipeline was just left out and a general
`SURVEY' variable was set and never used. So with this commit, we actually
use a sample FITS file from the FITS standard webpage, show it (as well as
its histogram) and do some basic calculations on it.

This preparation of the input datasets is done in a generic way to enable
easy addition of more datasets if necessary.
