+Improved: The vector operations in SolverIDR::solve() have been revised for
+performance.  The new implementation should show a speedup in case the
+matrix-vector product and preconditioner are not much more expensive than the
+vector operations. Furthermore, the usage of temporary vectors has been
+reduced by two.
