    <summary>A store for <see cref="T:Gtk.TreeView" /> that provides data from an arbitrary class.  It is simpler to use than the <see cref="T:Gtk.ListStore" />.</summary>
    <remarks>
      <para>
This class provides a simple mechanism of implementing the Model required by the <see cref="T:Gtk.TreeView" />.
</para>
      <example>
        <code lang="C#">
     [TreeNode (ColumnCount=2)]
     class DemoNode {
                string name;
                string email;

                public DemoNode (string name, string email)
                {
                        this.name = name;
                        this.email = email;

Iteration: In new versions of Gtk# (2.0 and up) this class implements the <see cref="T:System.Collections.IEnumerable" /> interface, so code can be written like this:
</para>
      <para>
        <example>
          <code lang="C#">
     void DumpColumnValues (NodeStore store, int col)
     {
         foreach (object[] row in store) 
              Console.WriteLine ("Value of column {0} is {2}", col, row [col]);
     }
