[Olena-patches] proto-1.0 168: Add features to nbhs and niters.

2005-04-27 Thierry GERAUD &lt;theo(a)tegucigalpa.lrde.epita.fr&gt; * oln/funobj/accum.hh (min_accumulator_init): New class. * oln/core/abstract/niter.hh (for_all_n_of_p): Fix bug. (set_type<image,I,niter_type>): New type deduction. (set_type<image,I,fwd_niter_type>): Likewise. (set_type<image,I,bkd_niter_type>): Likewise. * oln/core/abstract/neighborhood.hh (iter, fwd_iter, bkd_iter): New properties. * oln/core/gen/regular_neighborhood.hh: Update. * oln/core/abstract/window.hh (operator-): New. * oln/core/pw/image.hh (grid_type): New property. (concrete_type): Likewise.
