ply_to_tri_surface_test():
  MATLAB/Octave version 6.4.0
  Test ply_to_tri_surface().

ply_to_tri_surface_test01():
  ply_to_tri_surface() reads a PLY file.
  It can return a PLY data structure,
  or a pair ( NODE_XYZ, TRIANGLE_NODE )
  which is a simple triangular mesh.

  Extract nodes and triangles from "sphere.ply"

  The first 5 nodes:

ply_to_tri_surface_test02
  ply_to_tri_surface() reads a PLY file as TRI_SURFACE data.
  tri_surface_write() writes the data to a pair of TRI_SURFACE files.
