yeah, we should probably leave the release branch alone, except for 
triviality.

If I were to use the array_one() or array_two() functions, I would need 
to know which one that spanned the buffer given is_linearized() was 
true. (I pressume it would be array_one()). But, since the interface 
already exposes both normal and reverse iterators, it would be cool if 
it also worked for reverse iterators.

In Boost.Iterator, the wrapped iterators are accessible as iter.base(),
and I think it makes sense to reuse that scheme, just with a slightly 
different name.

So if is_linearized() is true, the following efficient ranges could be 
valid:

[begin().array_ptr(),end().array_ptr())
[rbegin().array_ptr(),rend().array_ptr())
