ELE2NEI - build a FEM neighbor list from element and node lists
   ELE2NEI computes the neighbor list for a FEM mesh specified
   by the triangular element lists.  Each node's neighbor list
   is then sorted into counter-clockwise order.

   The resulting neighbor list can be passed to WRITE_NEI
   to output a FEM neighbor file (.nei) to disk.

  INPUTS:  e - 3-column element connectivity list (REQ)
           x - x-coordinate list (REQ)
           y - y-coordinate list (REQ)
 OUTPUTS:  nei - neighbor list (REQ)

    CALL: nei=ele2nei(e,x,y);
