Overview

Given a Batch object representing a request to ‘print’ (ie compile) a PDF of multiple HD Session Forms (aka protocols), where each batch.item points to the patient we want to print, we render each PDF in the current folder (we assume the caller has chdir’ed us into a tmp location), and then append them all together as <batchid>.pdf in a known location. The filepath is assigned to the batch and saved, so it can be served to a user via the user later.
