Description

A non-owning reference to a range of code points that comprise a grapheme.

`grapheme_ref` public construct/copy/destruct

```
grapheme_ref() = default;
```
Default ctor.
```
grapheme_ref(iterator first, iterator last);
```
Constructs *this from the code points [first, last).

Requires:

The code points in [first, last) comprise at most one grapheme.
```
grapheme_ref(utf32_view< iterator > r);
```
Constructs *this from r.

Requires:

The code points in r comprise at most one grapheme.
```
grapheme_ref(grapheme const & g);
```
Constructs *this from g.

`grapheme_ref` friend functions

constexpr bool operator==(grapheme_ref lhs, grapheme_ref rhs);

Returns true if lhs the same sequence of code points as rhs.
