// Create the lookup table for the Marching Cubes algorithm that is used to
// extract a triangular mesh that represents a level surface of a 3D image
// sampled on a regular lattice.  The assumption is that no data sample is
// zero, which allows us to have a table with 256 entries: 2 signs per
// sample, 8 samples per volume element (voxel).  Each entry corresponds to
// the pattern of 8 signs at the corners of a voxel.  The signs are stored as
// bits (b7,b6,b5,b4,b3,b2,b1,b0).  The bit assignments to voxel corners is
//   b0 = (x,y,z),   b1 = (x+1,y,z),   b2 = (x,y+1,z),   b3 = (x+1,y+1,z)
//   b4 = (x,y,z+1), b5 = (x+1,y,z+1), b6 = (x,y+1,z+1), b7 = (x+1,y+1,z+1)
// If a bit is zero, then the voxel value at the corresponding corner is
// positive; otherwise, the bit is one and the value is negative.  The
// triangles are counterclockwise ordered according to an observer viewing
// the triangle from the negative side of the level surface.

// INTERNAL USE ONLY.  This is used for convenience in creating the
// Configuration table.  TODO: Expand the macro manually for the table
// creation.
