Construct an iterator.

1) Default constructor. Value-initializes the underlying data members:

- `current_` with ranges::iterator_t <Base>(),
- `last_ele_` with ranges::iterator_t <Base>() (note that this member may not be present),
- `n_` with ​0​.

2) Conversion from /*iterator*/<false> to /*iterator*/<true>. Initializes the underlying data members:

- `current_` with std:: `move` (i.current_),
- `n_` with i.n_.

Note that /*iterator*/<true> can only be formed when `Base` models /*slide-caches-nothing*/, in which case `last_ele_` is not present.
3) A private constructor which is used by ranges::slide_view::begin and ranges::slide_view::end. This constructor is not accessible to users. Initializes the underlying data members:

- `current_` with current,
- `n_` with n.

Note that this overload can only be present if `last_ele_` is not present.
4) A private constructor which is used by ranges::slide_view::begin and ranges::slide_view::end. This constructor is not accessible to users. Initializes the underlying data members:

- `current_` with current,
- `last_ele_` with last_ele (note that this data member is present due to /*slide-caches-first*/<Base> requirement),
- `n_` with n.

### Parameters

i | - | an /*iterator*/<false>
current | - | an iterator to current element of `slide_view`
last_ele | - | an iterator to last element of `slide_view`
n | - | the slide window width of `slide_view`
