tar_up_analysis_files.sh: New script to archive files

This script archives the analysis scripts and output files.

The following tarballs are created:
analysis_files.tgz
analysis_scripts.tgz

These tarballs can then be archived in Jira for example, to
allow the analysis to be repeated in future if necessary.
