TRIANGULATION_ORIENT
  MATLAB/Octave version 6.4.0
  Read a node dataset of NODE_NUM points in 2 dimensions.
  Read an associated triangle file of TRIANGLE_NUM 
  triangles using 3 or 6 nodes.

  Ensure that every triangle has positive orientation.

  Write the reoriented triangle file.

  Read the header of "p15_nodes.txt".

  Spatial dimension DIM_NUM = 2
  Number of points NODE_NUM = 614

  Read the data in "p15_nodes.txt".

  First 5 nodes:

  Read the header of "p15_elements.txt".

  Triangle order = 3
  Number of triangles TRIANGLE_NUM  = 1036

  No conversion is necessary.

TRIANGULATION_ORIENT - Warning!
  You have 512 triangles with
  negative area.

  We have reoriented these triangles to have positive
  area, and written the new triangle data to 
  the triangle file "p15_orient_elements.txt".
