**triangulation_triangle_neighbors_test**,
a C program which
calls triangulation_triangle_neighbors() to
compute the three neighboring triangles of each triangle in a triangulation.

triangulation_triangle_neighbors, a C program which reads data defining a triangulation, determines the neighboring triangles of each triangle, and writes that information to a file.

- triangulation_triangle_neighbors_test.sh, runs all the tests.
- triangulation_triangle_neighbors_test.txt, the output file.

**BOX3** is a triangulation of order 3:

- box3_nodes.txt, the node coordinates.
- box3_elements.txt, the triangulation;
- box3.png, a PNG image of the triangulation;
- box3_element_neighbors.txt, the neighbor triangles.
