library for structural biology

 Library for macromolecular crystallography and structural bioinformatics. For
 working with coordinate files (mmCIF, PDB, mmJSON), refinement restraints
 (monomer library), electron density maps (CCP4), and crystallographic
 reflection data (MTZ, SF-mmCIF). It understands crystallographic symmetries,
 it knows how to switch between the real and reciprocal space and it can do a
 few other things.
 .
 This package contains header-only C++ library.
