Allow cellline and conditition to be blank [ticket:115] [ticket:105]
However this requires a dump and reload of the database to work.

This saves the data as a django 'fixture'
python manage.py dumpdata samples > /tmp/sampledata.json
python manage.py sqlreset samples | sqlite3 [path to db]
python manage.py loadddata /tmp/sampledata.json
