[Olena-patches] 3197: Allow to construct 3D neighborhoods from C arrays.

https://svn.lrde.epita.fr/svn/oln/trunk/milena Index: ChangeLog from Thierry Geraud &lt;thierry.geraud(a)lrde.epita.fr&gt; Allow to construct 3D neighborhoods from C arrays. * mln/core/alias/neighb3d.hh: Upgrade file doc style. (from_to_): New overload. * mln/convert/from_to.hxx (from_to_): New fwd decl. * mln/make/box3d.hh (todo): New.
