PDBx:refine_histType

Data items in the REFINE_HIST category record details about the
steps during the refinement of the structure.
These data items are not meant to be as thorough a description
of the refinement as is provided for the final model in other
categories; rather, these data items provide a mechanism for
sketching out the progress of the refinement, supported by a
small set of representative statistics.

    Example 1 - based on laboratory records for the collagen-like
                peptide [(POG)4 EKG (POG)5]3.
