I'm not sure how, but in moving an index over from 2.0 to 2.1 and
changing my own code one of the .tii files got deleted. I still have
the .tis file though, can I rebuild the missing file so I can open my
index? Luke won't open it now and I just want to make sure everything
is ok before opening a writer and possibly doing some permanent damage.

In the interest if helping out the next person with this problem, here
is all my code to recover the missing .tii file when I still had the
rest of the index.
Of course now I am also missing one .fN norm file so I will be trying to
figure out how to recover that. Looks like everything else is there, I
have no idea how this happened.
