NGIS - WGS worklist functions > * move WGS section lab-tests to it's own function in worklist, now have many-to-one tests-to-section > * requires conversion of object to hashref (as_tree) in Model which also prevents unnecessary lookups on undef objects > * csv export function handles germline samples (uses original_diagnosis test in place of results summary) > * improve .tt handling of data (variables written to unwanted sections of request form)
