    /// interface.  It does not hold any data itself, but rather is created with
    /// a child model and proxies its data.  It has identical column types to
    /// this child model, and the changes in the child are propagated.  The
    /// primary purpose of this model is to provide a way to sort a different
    /// model without modifying it. Note that the sort function used by
    /// [`TreeModelSort`][crate::TreeModelSort] is not guaranteed to be stable.
    ///
    /// The use of this is best demonstrated through an example.  In the
    /// following sample code we create two [`TreeView`][crate::TreeView] widgets each with a
    /// view of the same data.  As the model is wrapped here by a
    /// [`TreeModelSort`][crate::TreeModelSort], the two [`TreeView`][crate::TreeView]s can each sort their
    /// view of the data without affecting the other.  By contrast, if we
