obj_io_test():
  MATLAB/Octave version 5.2.0
  Test obj_io().

obj_io_test01():
  obj_size() determines the size of various objects
  in an OBJ file.

  Object sizes for OBJ file "cube.obj":

  Nodes              = 8
  Faces              = 12
  Maximum face order = 3
  Normal vectors     = 6

obj_io_test02():
  obj_read() reads an object in an OBJ file.
