FEM_SAMPLE_TEST01:
  Evaluate a finite element function on a uniform grid.

  This function expects to find three files to read:

  * node_file,      containing the node coordinates,
  * triangle_file,  containing triples of nodes that form triangles,
  * coef_file,      containing nodal coefficient values.

  It reads the files and makes plots of:

  * the triangulation,
  * a crude contour plot that is constant over each triangle, and
  * a nicer contour plot that uses interpolation.

  The node file is "nodes.txt".
  The triangle file is "triangles.txt".
  The coefficient file is "coefs.txt".
  The number of nodes is 25
  The triangle order is 3
  The number of triangles is 32

  Requested   node density = 4
  Suggested X node density = 4
  Suggested Y node density = 4

  X sample coordinates:

    0.000000  1.333333  2.666667  4.000000

  Y sample coordinates:

    0.000000  1.333333  2.666667  4.000000

  U evaluated at sample points:

     16.000000   18.000000   23.333333   32.000000
      7.333333    9.333333   14.666667   23.333333
      2.000000    4.000000    9.333333   18.000000
      0.000000    2.000000    7.333333   16.000000

FEM_SAMPLE_TEST
  Normal end of execution.
