[phenixbb] continuously Rfree lower than Rwork

[Pavel Afonine]

It may mean a variety of things, such as:

- troubled refinement, incorrect target weights for instance;
- suboptimal model parametrization or/and optimization method choice;
- incorrect test/work flag use in refinement;
- this sometimes happens if you refine against ultra-high resolution 
(higher than say 0.7A).

If you send more information such as at least refinement log and eff 
files then it may be possible to tell more.
