Creates precomputed tables for all possible configurations of the neighborhood of a voxel in 3D with a topology of 26 neighbors. The table is a map between all this configurations and the result of applying an input selected predicate function to a center voxel. The options for the functions are the Skel function from

See also

VoxelComplexFunctions.h.

The options are: skelFunction = functions::oneIsthmus<VoxelComplex>; skelFunction = functions::twoIsthmus<VoxelComplex>; skelFunction = functions::skelIsthmus<VoxelComplex>;

where the latest is equivalent to (oneIsthmus OR twoIsthmus)

Isthmuses are implemented to work with 3D cubical(voxel) complexes. Right now the tables are only generated with 26_6 topology, but other 3D topologies can be added.
