triangulation_boundary_edges():
  MATLAB/Octave version 5.2.0
  Identify triangulation edges on the boundary.

* Read a dataset of NODE_NUM points in 2 dimensions;
* Read an associated triangulation dataset of  
  triangles using 3 or 6 nodes;
* Determine which edges are on the boundary;
* Write a file: segment_index, node1_index, node2_index.

  Read the header of "ell_nodes.txt".
  Spatial dimension DIM_NUM = 2
  Number of nodes NODE_NUM  = 65
  Read the data in "ell_nodes.txt".

  Read the header of "ell_elements.txt".
  Triangle order = 3
  Number of triangles = 96
  Read the data in "ell_elements.txt".

  Wrote the boundary edge file "ell_boundary_edges.txt".
