Hyperlinks to collections

[jasujm]

I'd like to be able to write

class Library(BaseReferrableModel):
    id: id
    books: Href[List[Books]]

and make the hyperlink resolve to URL of the list (for example "http://example.com/libraries/1/books") instead of list of URLs (for example ["http://example.com/books/1", "http://example.com/books/2"]. Note the difference of Href[List[Book]] and List[Href[Book]].

The setup needs careful consideration. A singular resource (such as Book) can be assumed to have a single canonical URL, but the URL of a collection depends on the context (such as all books in a library, all books by an author, etc.).
