Woops! Sorry in case I just confused a lot of people. The number Felix
reports: n_xtals = 0.078 means that the structure solution should have
been "easy" (I.E. it could have been done with a crystal having only 8%
of the volume used), and indeed it sounds like it was a slam dunk. So,
it sounds like Felix got a good prediction from it.

However, I am still very interested if anyone can solve a structure from
a case where my predictor says that you can't.
