[emacs-humanities] Improved oref.el (quick reference/citation system for text files)

[Karl Fogel]

Hi, everyone.  I posted about the initial version of this tool a 
year ago (see thread "oref.el: quick reference/citation management 
in plaintext files" at [1]).

Now it's significantly improved:

Building the reference cache now happens in the background, i.e., 
asynchronously.  Even if you have references across a very large 
tree, you can continue to use Emacs normally while the reference 
cache is rebuilding (when it's done, oref will notify you, with 
`display-buffer'.)

So, you can put something like...

 (oref-rebuild-refs my-huge-projects-folder)

...into your .emacs, without affecting Emacs startup time.

I hope others find this package useful.  My company uses it 
extensively in LaTeX documents and in research notes, FWIW.

Questions / bug reports / patches welcome, as always.  You can get 
oref.el here:

Best regards,
-Karl
