This is not really a LaGriT example input file. It is a graphical representation
of the node graph of a mesh that is reordered using the line sweep algorithm in
the LaGriT sort command. LaGriT does not presently have the cabability of
creating these graphics. This was done using a hacked together piece of
code to force LaGriT to write the node graph as a GMV graphics file. The
graphics show the structure of the sparse matrix for an apx. 350,000 node
mesh before and after reorder.
