alignment.append_model() -- copy model sequence and coordinates to alignment

mdl = <model>		model to read sequence from
align_codes = <str:0>	'all'	codes of proteins in the alignment
atom_files = <str:0>	''	complete or partial atom filenames

Description:

This command adds the sequence and coordinates of the given model, mdl, to the end of the current alignment.

You should additionally set align_codes and atom_files to the PDB ID and file name, respectively. This information is added to the alignment with the new sequence. (Alternatively, you can set this information later by setting alignment[x].code and alignment[x].atom_file, where 'x' is the index of the sequence in the alignment, starting at zero.)

Example: See alignment.compare_with() command.
