Make the link between raw data and computed data visible

[monsieurtanuki]

Why - Problem description

OFF provides many raw data (e.g. ingredients) and many computed data (e.g. Nutriscore).
The links between raw data and computed data is invisible.
Users may have very different interests, like Ecoscore or Nova.
It would help user contributions if we could say to them: "You're only interested in Nova? Then you only have to enter the ingredients."

What - Proposed solution

• list the computed fields
• for each computed field, list the actions potentially needed (cf. KP actions)
• as a bonus, do this at the product level ("I have this product, I want to compute its nutriscore, which data should I enter?")
