v2.7.0

This release mainly introduces compatibilities with other packages dedicated to crystallographic analyses, namely:

• pymatgen,
• orix.

Evaluation of statistics for SphericalFunction and HyperSphericalFunction (e.g. .mean() or .std()) now take advantage of broadcasting, therefore speeding them up (~10 times faster).

The input matrix for creating a StiffnessTensor or a ComplianceTensor now must be symmetric and definite positive (except if check_symmetry=True and check_positive_definite=False, respectively).

Full Changelog: v2.6.0...v2.7.0

v2.6.0

• Faster statistics on SphericalFunction and HyperSphericalfunction.
  In details, they use "home-made" integration, taking advantage of broadcasting

• Possibility to reuse existing XYZ sections in SphericalFunction.plot_xyz_sections()
