[Olena-patches] 2146: Add a missing (disabled) conversion method to mln::any_face_handle.

https://svn.lrde.epita.fr/svn/oln/trunk/milena Index: ChangeLog from Roland Levillain &lt;roland(a)lrde.epita.fr&gt; Add a missing (disabled) conversion method to mln::any_face_handle. * mln/core/complex.hh: Make mln::any_face_handle a friend of mln::complex. * mln/core/face.hh (mln::any_face_handle<D>::to_face<N>): New method. Exercise it... * tests/core/complex.cc: ...here.
