Quality API

DRAFT

We introduce a new concept: "Candidate ingredient list". Those are ingredients list from mobile, generated by OCR, more or less trustworthy, that are not displayed on the Web version, nor in the ingredient list in the API, but are available in a specific API field.

It is strongly discouraged to use it as a substitute for ingredients lists. People may use it for gamification: get your users to check one another's contributions..
