What I vaguely remember from a solid state physics course long ago is that
the Miller indices of a plane, for all but non-cubic lattices, are just
vector coefficients of the normal to the plane. So couldn't the Miller
indices be input directly into the PlaneNormal argument of EXTRACT_SLICE? I
haven't tried, but it would seem that the other input needed is Xvec,
indicating something like the X direction of the plane grid, I think.

I'm no expert at all, but the thread seemed so silent...
