Construct an iterator.
1) Default constructor. Value-initializes the 
parent_ with nullptr and default-initializes the current_.2) Conversion from /*iterator*/<false> to /*iterator*/<true>. Initializes 
parent_ with i.parent_ and current_ with std::move(i.current_).3) A private constructor which is used by cartesian_product_view::begin and cartesian_product_view::end. This constructor is not accessible to users.
Initializes 
parent_ with std::addressof(parent) and current_ with std::move(current).Parameters
| i | - | an /*iterator*/<false> |
