- To use TetGenGetNeigbors, you first need to load it using Needs["TetGenLink`"].
- TetGenGetNeigbors returns a list of a list of integers that specify which tetrahedra are next to each other. An entry of
indicates that the respective tetrahedron is on the boundary. - TetGenGetNeigbors needs the "n" switch to be set during the call to TetGenTetrahedralize.

This creates an instance of a TetGen expression:
This sets up points and facets to use:
This sets the points and facets in the TetGen instance:
This carries out the tetrahedralization, returning a new TetGen instance. The switch "n" requests TetGen to compute the neighbors:
This extracts the points and elements from the tetrahedralization:
This is a list of the neighboring elements, with 
indicating a boundary:
