Support for Howell-Rutherford or Howell-Boeing Sparse matrix format

     We have not provided supported library routines for this since  
we've found that actual ASCII file formats often
require slightly different readers. And thus we could not provide  
robust readers. Instead we have some example
routines in src/mat/examples/tutorials/, specifically ex78.c that the  
user may modify for their exact needs.

   I've added this information to our FAQ.
