Multiprocessing and Python3.7
In this release:
- Multiprocessing is used by default to make slab generation and parsing of large data files faster
- Automated plots are generally neater
- Bugs have been removed from command line tools
- We specify python3.7 is required for future-proofing reasons
- We have updated the way core pymatgen classes are imported, again for future-proofing reasons (see the pymatgen announcement compatibility)
