+       New: A class <code class="class">PreconditionLU</code> which
+       provides a wrapper to the complete LU decomposition
+       preconditioner of PETSc. Furthermore a class 
+       <code class="class">SolverPreOnly</code> was implemented. It
+       is a wrapper for the PETSc solver type KSPPREONLY, which
+       only applies the preconditioner. In conjunction with
+       <code class="class">PreconditionLU</code> this provides a
+       simple direct solver, which could be used for small to medium
+       sized problems on a single processor machine.
