  test triangulation_boundary();

triangulation_ijk_to_node_test:
  triangulation_ijk_to_node receives the IJK coordinates
  of triangles in a triangulation.
  It creates a triangular grid, assigns a number to each
  node on the grid, and returns a list of the node numbers
  forming each triangle in the triangulation.

  Nodes making up each triangle:

   1:   7   6   2
   2:   6   7  11
   3:  12  11   7
   4:  11  12  16
   5:  17  16  12
   6:   2   3   7
   7:  12  13  17
   8:  18  17  13
   9:  14  13   9
  10:  13  14  18
  11:  19  18  14
  12:  10   9   5
  13:   9  10  14
  14:  15  14  10
  15:  14  15  19

triangulation_node_to_boundary_edge_test:
  triangulation_node_to_boundary_edge receives the indices
  of the vertices of triangles in a triangulation.
  It returns boundary edges as pairs of node indices.

  Boundary edges (pairs of nodes):

   1:   2   3
   2:   6   2
   3:   3   7
   4:   9   5
   5:   5  10
   6:  11   6
   7:   7  12
   8:  13   9
   9:  10  15
  10:  16  11
  11:  12  13
  12:  15  19
  13:  17  16
  14:  18  17
  15:  19  18

boundary_edge_to_path_test:
  boundary_edge_to_path receives a list of pairs
  of nodes constituting boundary edges of the triangulation.
  It returns a list of nodes that form a counterclockwise
  path around the boundary.  It also reorders the edge list.

  Nodes in the boundary path:

   1:   2
   2:   3
   3:   7
   4:  12
   5:  13
   6:   9
   7:   5
   8:  10
   9:  15
  10:  19
  11:  18
  12:  17
  13:  16
  14:  11
  15:   6

  Reordered boundary edge list (pairs of nodes):

   1:   2   3
   2:   3   7
   3:   7  12
   4:  12  13
   5:  13   9
   6:   9   5
   7:   5  10
   8:  10  15
   9:  15  19
  10:  19  18
  11:  18  17
  12:  17  16
  13:  16  11
  14:  11   6
  15:   6   2

node_to_ij_test
  node_to_ij() takes a temporary scalar node index
  and computes the (I,J) parallelogram indices.
