Changed

• Removed degrees argument to BravaisLattice constructor, since it doesn't do anything.

Added

• Sites class used from spatial-sites package for internally storing lattice sites.

Changed

• To be consistent with the new Sites class, the BravaisLattice attribute row_or_column has changed to vector_direction, and it now accepts "col" in addition to "column".

Fixed

• Cubic lattices can now have the body-centred (I) centring type.

Changed

• Added an American-spelt version of the BravaisLattice attribute centring_type: centering_type.
• Lattice parameters a, b, c, alpha/α, beta/β and gamma/γ, lattice_system and centring_type/centering_type are now properties and therefore cannot be modified after instantiation.

Fixed

• row_or_column attribute is now respected by lattice_sites and lattice_sites_frac attributes.
• Deprecation warning from pyyaml has been resolved.

Changed

• This is the initial "complete" version; PyPI "development status" has been changed from "3 - Alpha" to "4 - Beta".
