Tinker XYZ format (txyz)

The cartesian XYZ file format used by the molecular mechanics package TINKER.

By default, the MM2 atom types are used for writing files but MM3 atom types are provided as an option. Another option provides the ability to take the atom type from the atom class (e.g. as used in SMILES, or set via the API).
