w90_kpath Module

Calculates quantities along a specified k-path:

Energy bands (eventually colored by the spin)
Energy bands (colored by Berry curvature-like term of spin Hall conductivity)
(Berry curvature)x(-1) summed over occupied bands
Berry curvature-like term of spin Hall conductivity summed over occupied bands
Integrand of orbital magnetization Morb=LCtil+ICtil
