mesh2d_write_test():
  MATLAB/Octave version 6.4.0
  Use mesh2d() to create a mesh for the L-shaped region.
  Then write the information to node and element files.

mesh2d_write_test01()::
  Minimal input
  6 boundary vertices
  21 nodes and 24 triangles created
  Nodes stored as "mesh1_nodes.txt"
  Elements stored as "mesh1_elements.txt"

mesh2d_write_test02():
  Same shape as test #1, but set a few small boundary
  segments, where mesh will be refined.
  8 boundary vertices
  43 nodes and 57 triangles created
  Nodes stored as "mesh2_nodes.txt"
  Elements stored as "mesh2_elements.txt"

mesh2d_write_test03():
  same geometry as test #1,
  but set maximum element size HDATA.HMAX = 0.1
  6 boundary vertices
  225 nodes and 384 triangles created
  Nodes stored as "mesh3_nodes.txt"
  Elements stored as "mesh3_elements.txt"

mesh2d_write_test04():
  Repeat example #1, but now specify small elements 
  near reentrant corner using a size function.
  6 boundary vertices
  979 nodes and 1850 triangles created
  Nodes stored as "mesh4_nodes.txt"
  Elements stored as "mesh4_elements.txt"

mesh2d_write_test05():
  Repeat example #1, then call refine ( ).
  6 boundary vertices

  Initial triangulation has:
  21 nodes
  24 triangles

  Refined triangulation has:
  65 nodes
  96 triangles
  65 nodes and 96 triangles created
  Nodes stored as "mesh5_nodes.txt"
  Elements stored as "mesh5_elements.txt"

mesh2d_write_test06():
  Repeat example #2, then call smoothmesh ( ).
  8 boundary vertices
  43 nodes and 57 triangles created
  Nodes stored as "mesh6_nodes.txt"
  Elements stored as "mesh6_elements.txt"

mesh2d_write_test07():
  Channel with baffles, max element size is 0.50.
  82 boundary vertices
  82 edges
  510 nodes and 870 triangles created
  Nodes stored as "mesh7_nodes.txt"
  Elements stored as "mesh7_elements.txt"

mesh2d_write_test():
  Normal end of execution.
