Solves two linear systems in parallel with KSP.  The code<BR>illustrates repeated solution of linear systems with the same preconditioner<BR>
method but different matrices (having the same nonzero structure).  The code<BR>
also uses multiple profiling stages.  Input arguments are<BR>
  -m &lt;size&gt; : problem size<BR>
  -mat_nonsym : use nonsymmetric matrix (default is symmetric)<BR>

The solution of 2 different linear systems with different linear solvers.<BR>Also, this example illustrates the repeated<BR>
solution of linear systems, while reusing matrix, vector, and solver data<BR>
structures throughout the process.  Note the various stages of event logging.<BR>
