/// Checks if `rhs` is completely contained within the interior of `self`.
///
/// More formally, the interior of `rhs` has non-empty
/// (set-theoretic) intersection but neither the interior,
/// nor the boundary of `rhs` intersects the boundary nor exterior of
/// `self`. In other words, the [DE-9IM] intersection matrix
/// of `(rhs, self)` is `T**FF*FF*`.
///
/// [DE-9IM]: https://en.wikipedia.org/wiki/DE-9IM
///
/// # Examples
///
/// ```
/// use geo::ContainsProperly;
/// use geo::{line_string, point, Polygon};
///
/// let line_string = line_string![
///     (x: 0., y: 0.),
///     (x: 2., y: 0.),
///     (x: 2., y: 2.),
///     (x: 0., y: 2.),
///     (x: 0., y: 0.),
/// ];
///
/// let polygon = Polygon::new(line_string.clone(), vec![]);
///
/// // Point in Point
/// assert!(point!(x: 2., y: 0.).contains_properly(&point!(x: 2., y: 0.)));
///
/// // Point in Linestring
/// assert!(line_string.contains_properly(&point!(x: 2., y: 0.)));
///
/// // Point in Polygon
/// assert!(!polygon.contains_properly(&point!(x: 2., y: 0.)));
/// assert!(polygon.contains_properly(&point!(x: 1., y: 1.)));
/// ```
///
/// # Performance Note
///
/// Much of this trait is currently implemented by delegating to the [`Relate`](crate::algorithm::Relate) trait - see
/// [`IntersectionMatrix::is_contains_properly`](crate::algorithm::relate::IntersectionMatrix::is_contains_properly);
/// `ContainsProperly` is faster when checking between `Polygon` and `MultiPolygon` when inputs are smaller than about 650 vertices, otherwise use [`Relate::relate().is_contains_properly`](crate::algorithm::relate::IntersectionMatrix::is_contains_properly).
