It turns out that that's not the nice little finger exercise to
reward oneself right before going home.  Surprisingly, it's actually
a bit of code and conceptially fairly complicated.

I've now cobbled together a function and a couple of tests that's
perhaps not ultra-robust and needs some review (attached, use
whatever license you need).  And... well, would anyone volunteer to
massage that into astropy?  I have a bit of stagefright when it comes
to their io.votable module, in particular when it's about introducing
a function we don't even need just now...

Thanks,

          Markus
