Bio Files: Read and write common biology file formats

Currently supported:

• Mol2 (Molecules)
• Map (Electron density, e.g. from crystallography)
• AB1 (Sequence tracing)

Planned:

• SDF
• PDBQT
• MTZ
• DNA
• CIF auxiliary formats (2fo-fc etc)

For Genbank, we recommend GB-IO. For atom coordinate mmCIF and PDB, we recommend PDBTBX. We do not plan to support these in these formats in bio_files due to these high-quality libraries.
