triangulation_node_to_element():
  Fortran77 version
  Average nodal data to create element data.

  This program expects three files:

  * prefix_nodes.txt,    node coordinates,
  * prefix_elements.txt, indices of nodes forming elements,
  * prefix_values.txt,   data values at nodes.

  It creates:

  * prefix_element_values.txt, averaged data at elements.
 
  Read the header of "lake_nodes.txt".
 
  Spatial dimension DIM_NUM =        2
  Number of nodes NODE_NUM  =      621
