Comment 18 for bug 2015484

Here's a link to the rebased branch as promised: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/collab/dyrcona/lp2015484_exclude_opac_visible_from_export-rebase

I've tested this with a couple of our regular exports and it gives me results similar to what I expect from the production code.

I'm still testing it, but I think we'll want to use the rebase branch if the code from bug 2041364 got in first.

In fact, that's my preferred order for merging the code.

Edited to add that I'm also "testing" this in production. I think the above is working rather well.
