@kimberlyh66 @dlebauer Review and make into an Epic if needed, before Sprint 2 begins

Need to

• identify missing methods
• create records in methods table
• write queries to update traits table so that all traits are associated w/ the correct method
• create issues / epic for documenting protocols more generally
