Scientific study resource

[ascariandrea]

In order to keep track of the evolving science for a specific topic there's need to have a new resource ScientificStudy.

It's shape should be similar to:

const ScientifiStudy = t.strict({
 source: URL,
 title: t.string,
 abstract: t.string,
 conclusions: t.string,
 publishedAt: Date,
 authors: t.array(UUID) // actors uuids
}, 'ScientificStudy')

The related endpoints and routes should be implemented as other resources.
