TRIANGULATION_REFINE
  MATLAB version
  Read a "linear" or "quadratic" triangulation
  and write out a refined triangulation.

  Read a dataset of NODE_NUM1 points in 2 dimensions.

  Read an associated triangulation dataset of TRIANGLE_NUM 
  triangles which uses 3 or 6 nodes per triangle.

  Subdivide each triangle into 4 triangles,
  generate new nodes as midpoints of current nodes.

  Write out the new node and triangulation data.

  If the input triangulation was Delaunay, then
  the output triangulation will be Delaunay.

  Read the header of "box_order3_nodes.txt".

  Spatial dimension DIM_NUM = 2
  Number of points NODE_NUM1  = 20

  Read the data in "box_order3_nodes.txt".
