Returns ID of newly created item
Depending on context, may wish to deactivateAnalysis of component items once this composite one is created

Newly created composite item's default_recommend attribute will be reset to 0 since it presumably does not represent a
discrete order item.
Linking records will be created in clinical_item_link between the composite and and component clinical items
so that these relationships can be reconstructed
Examples this could be relevant for:
ICUVasopressors to include all vasopressor infusions (dopamine, norepinephrine, epinephrine, vasopressin, etc.)
All blood transfusion indexes, G vs J vs Feeding tube equivalent, Ear, Eyes med routes irrelevant which ear/eye.
Eventually lump together medication classes (e.g., any "PPI" same difference as choosing pantoprazole or omeprazole.
Eventually lump together diagnosis codes by major prefix to reduce granularity and improve general signal.
