TRIANGULATION_BOUNDARY_NODES
  MATLAB version

  Identify triangulation nodes 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 nodes are on the boundary;

* Write a file which is 1 for each boundary node.

  Read the header of "lake_nodes.txt".

  Spatial dimension DIM_NUM = 2
  Number of nodes NODE_NUM  = 621

MESH_BASE_ONE:
  The element indexing appears to be 1-based!
  No conversion is necessary.

  Number of boundary nodes is 268

  Wrote the node boundary value file "lake_boundarynodes.txt".
