this needs to be split into individual CCD files - one for each chemical component.
these then need to be processed to sdf/pdb and images.
How
It might be sensible to do this by parsing the complete file using a cif parser - could then process each component using the tools developed to write sdf, pdb files and images. If so could address issue #10 (closed) at same time.
Or it might be necessary to split the file into individual small files in a separate program without using cif parser each component starts with line data_ABC where ABC is the chem_comp.id (aka residue name).
