Deconflation endpoint

[cbizon]

Conflation can be a useful tool for representing knowledge in a database, but it is sometimes not a good fit for the presentation layer. For instance, our gene/protein conflation minimizes the number of hops in a database query, but sends shivers down the spine of every good biologist.

One tool that may help would be a deconflation endpoint. Given the clique leader of a conflated clique, return the cliques that are conflated into this original clique.

Bonus points for returning the relationship between the deconflated cliques (has_product, has_active_ingredient).
