Python Materials Genomics is a robust materials analysis code that defines
core object representations for structures and molecules with support for
many electronic structure codes.

This is the pymatgen-core package, which implements the core data structures
and algorithms of pymatgen, including:
- Core data structures (Structure, Molecule, Element, etc.)
- Electronic structure modules
- IO modules for VASP, FEFF, CP2K, LAMMPS and more
- Symmetry analysis
- Transformation modules
- Optimization utilities
