Comment 1 for bug 1951318

Working branch user/jeffdavis/lp1951318-retrieve-carousel-items has a work-in-progress implementation of such a method:

https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/jeffdavis/lp1951318-retrieve-carousel-items

No pullrequest yet since this needs testing to ensure it returns data usefully and doesn't break existing carousel display. I won't have more time to devote to this in the immediate future, so if someone else feels like looking at it in the meantime, please feel free. :)
