=begin -------------------------------------------------------------------------
Generates spreadsheet on Roche Gallium trial cases. Assumptions for cases referred
to Kiel: if diagnosis is, or was, "Gallium trial - referred to Kiel", date of
referral = authorisation date. If diagnosis subsequently updated, then return date
assumed to be date of diagnosis change (taken from request_diagnosis_history table
where entry = "Gallium trial - referred to Kiel")
