Nonlinear Radiative Transport PDE with multigrid in 2d.<BR>Uses 2-dimensional distributed arrays.<BR>
A 2-dim simplified Radiative Transport test problem is used, with analytic Jacobian. <BR>
<BR>
  Solves the linear systems via multilevel methods <BR>
<BR>
The command line<BR>
options are:<BR>
  -tleft &lt;tl&gt;, where &lt;tl&gt; indicates the left Diriclet BC <BR>
  -tright &lt;tr&gt;, where &lt;tr&gt; indicates the right Diriclet BC <BR>
  -beta &lt;beta&gt;, where &lt;beta&gt; indicates the exponent in T <BR>
