-need a display of the dispersion in 2D UTBs in the new unidirect visualization
-need to extract the masses from the few lowest bands in the dispersion and find some critical minima in the dispersion. Then plot those minimum energies and masses as scatter plots on a diagram. Then a user can change the geometry or strain or gating and see how the minima or the masses vary as multiple simulations emerge.
