% Quick method to generate cell array with hole locations and radii on each
% planar face of "ScalarBasis". It should be possible to extract this data
% automagically, but that's tedious and dangerous.
%
% Each hole is given by a list of (x,y,z,r), with coordinates in model-space

Unfortunately, the first selection group in my standard model is the
mumetal layer itself, so the Comsol planar face selection grouping is off
by one from the 1-ordered Matlab list. Take the matlab index, and return
the specified hole pattern when appropriate.

-x face: Comsol-2, Matlab-1
-y face: Comsol-3, Matlab-2
-z face: Comsol-4, Matlab-3
+x face: Comsol-5, Matlab-4
+y face: Comsol-6, Matlab-5
+z face: Comsol-7, Matlab-6
