/// the `NcReel`, and zero or more `NcTablet`s.
///
/// An `NcReel` is a [`Notcurses`][crate::Notcurses] region devoted to
/// displaying zero or more line-oriented, contained [`NcTablet`]s
/// between which the user may navigate.
///
/// If at least one `NcTablet`s exists, there is a "focused tablet".
/// As much of the focused tablet as is possible is always displayed.

/// If there is space left over, other tablets are included in the display.
/// Tablets can come and go at any time, and can grow or shrink at any time.
