KSPMonitorSolution
Monitors progress of the KSP solvers by calling VecView() for the approximate solution at each iteration.
Synopsis
#include "petscksp.h"
PetscErrorCode KSPMonitorSolution(KSP ksp,PetscInt its,PetscReal fgnorm,void *dummy)
Collective on KSP
Input Parameters
 ksp   the KSP context

 its   iteration number

 fgnorm   2norm of residual (or gradient)

 dummy   either a viewer or NULL

Notes
For some Krylov methods such as GMRES constructing the solution at
each iteration is expensive, hence using this will slow the code.
