I doubt that the array parameter should ever be NULL, so you could use a
reference parameter here.  (The 'array_' member should still be a pointer.)
Either way, should this count as a conversion?  If not, make the constructor
explicit.

Should flattened_array be a friend of array?  If not, then flattened_array
has to work by translating array indices.  If it does use indices, then we
could offer a FORTRAN-order version along with the normal (C-order) version.
FORTRAN-order puts the fastest index first instead of last.
