Move waters to symmetry position closest to protein.
In crystallography it often happens that a water that sits
at the right side of the molecule is actually the same as a
water that sits at the left side. This server puts the waters
that can sit at several seemingly equivalent positions at that
position where it makes the closest contact with the protein.
