V2.3.0 - The user can now opt for considering or not considering the atomic positions when cheking the symmetries of the pc and SC. BandUP can now suggest prim. cells for the SC and reference unit cell provided by the user. A new colormap (flame) has been added to the plotting tool (still testing), thanks to Manfred Matena. Some changes in the symmetry-related routines. Major changes in the pre-processing tool to find the SC-Kpts. All changes are backwards compatible.
