(feat): Add org-ref citation support

[jethrokuan]

Motivation for this change

Add support for viewing backlinks on citations. This is a follow up on #130.

Very cool.

Can I just ask a high-level question, which might inform how you document this?

What's the difference between a cite and backlink, conceptually? They're both references, but how do they differ?

[jethrokuan]

One are file links, and the other are cite: links generated by org-ref.

[bdarcus]

So the "file links" are really (at a higher level) links of two notes. The cite: links are links between notes and (I guess more abstract) bibliographic sources, which may themselves have notes? The practical import of the question is how I can best structure all this. I tentatively setup things so I have a biblio subdir, where I put individual bib notes. So I'm just trying to understand how best to do linking within those bib notes. Is it likely I'd want to liberally include cite: links AND link to their related notes?

[jethrokuan]

I'd cite where the source is indeed that particular reference, and use file links everywhere else. cite: links is not a thing invented by org-roam, it's an org-ref thing. There's some discussion on Slack about getting org-ref's note-taking capabilities and org-roam to play nicely, but I haven't looked at it myself.

OK, that's helpful.

So in that case, using the cite: link is effectively a way to designate an org-roam note as a bibliographic note.
