## Description

### `istream_line_iterator` construct/copy/destruct

1.     istream_line_iterator();

   Effects: | ストリーム終端反復子を構築する。

2.     explicit istream_line_iterator(istream_type& is);

   Effects: |
       in_stream = &is;
       delim = is.widen('\n');
       std::getline(*in_stream, value, delim);

3.     istream_line_iterator(istream_type& is, CharT delimiter);

   Effects: |
       in_stream = &is;
       delim = delimiter;
       std::getline(*in_stream, value, delim);

### `istream_line_iterator` operators

1.     implementation defined operator*() const;

   Returns: | `value`

2.     istream_line_iterator<CharT,Traits,Allocator>& operator++();

   Effects: | `std::getline(*in_stream, value, delim)`
   Returns: | `*this`
