If Stonewall Jackson had lived?

Specifically... what changes to the war would the survival of Stonewall Jackson had (uming he had not been shot at all). There are many speculations about changes during Gettysburg, but the war would have continued despite a confederate win at Gettysburg. So my question (long or short explanation) is what would the American Civil War played out, look like, had Stonewall Jackson went unhed until the end of the war.
