Importer for the PDBx/mmCIF file format.

Parsing cif files in the PDBx/mmCIF format is done thanks to the GEMMI library.

Note that this importer does not yet support the creation of bio-assemblies.

If you want to import cif files for crystals you can use the cif importer provided with the Crystal Creator.
