Collective on SNES

	snes	- iterative context obtained from SNESCreate()
	viewer	- the viewer to display the reason

	-snes_converged_reason	- print reason for converged or diverged, also prints number of iterations
	-snes_converged_reason ::failed	- only print reason and number of iterations when diverged

To change the format of the output call PetscViewerPushFormat(viewer,format) before this call. Use PETSC_VIEWER_DEFAULT for the default, use PETSC_VIEWER_FAILED to only display a reason if it fails.
