This module contains variables and subroutines to perform the same tasks as the Quantum Espresso post-processing program "pw2wannier90", but using symmetries.
In particular, this module contains: - subroutines and variables for reading and storing $seed.nnkp file data. - subroutines for producing the $seed.mmn and $seed.amn files using only the wave functions in the IBZ, rotating them appropriately.
