From Aurélien Chatelain, "the smoothing visitor did not handle shared arrays. It may leads to bad geometry arrays when a shared array is involved in the scene.

This submission adds shared array duplication (and moves the SharedArrayOptimizer declaration in MeshOptimizer to make it callable from the SmoothingVisitor)."

Submitted by Marc Helbling.
Edited by Robet Osfield to retain the usual OSG coding style.
