Display list of collaborators for an author

[Codain]

Describe the problem that you'd like solved

I would like to know with who an author is frequently collaborating.

Proposal & Constraints

On an author page, have a list of other authors who have written a book with this author, sorted by number of work written together decreasing.

List can be formatted like the author list on a subject page or like an author list in a search result page (mode 'All').
