Description

Represents a forward-iterable view of non-overlapping code point subranges. Each subrange represents the code points between one allowed line break and the next. Each subrange is lazily produced; an output subrange is not produced until an iterator is dereferenced. Each element has a member function bool hard_break() that indicates whether the end of the subrange is at a hard line break, or just an allowed line break location. If forward_line_break_view is constructed with a stateful CPExtentFunc, you can get it back by moving it out via extent_func().

`forward_line_break_view` public construct/copy/destruct

```
forward_line_break_view();
```

forward_line_break_view(CPIter first, CPSentinel last, Extent max_extent, 
                        CPExtentFunc cp_extent, bool break_overlong_lines);

`forward_line_break_view` public member functions

```
iterator begin() const;
```
```
sentinel end() const;
```
```
CPExtentFunc extent_func();
```
Moves the contained CPExtentFunc out of *this.
