doped module (__init__.py)

doped is a python package for managing solid-state defect calculations, with functionality to generate defect structures and relevant competing phases (for chemical potentials), interface with ShakeNBreak (https://shakenbreak.readthedocs.io) for defect structure-searching (see https://www.nature.com/articles/s41524-023-00973-1), write VASP input files for defect supercell calculations, and automatically parse and analyse the results.
