I extended the spirit of Olaf's shared_array2 implementation quite a
bit so that it really is a smart resource-managing iterator_range
called shared_range.  The implementation (with documentation) and
tests are up at https://github.com/RhysU/shared_range.  I've opted to
move resource allocating operation's like Olaf's shared_array2(size_t)
constructor into free functions in the spirit of make_shared and
allocate_shared.

Olaf, I've added your name to the implementation header in
shared_range.hpp.  Please let me know if that's not okay with you.

Any feedback (or edge cases I've missed) greatly appreciated,
Rhys
