/**
 * The #GtkTreeStore object is a list model for use with a #GtkTreeView
 * widget.  It implements the #GtkTreeModel interface, and consequentially,
 * can use all of the methods available there.  It also implements the
 * #GtkTreeSortable interface so it can be sorted by the view.  Finally,
 * it also implements the tree
 * [drag and drop][gtk3-GtkTreeView-drag-and-drop]
 * interfaces.
 * 
 * # GtkTreeStore as GtkBuildable
 * 
 * The GtkTreeStore implementation of the #GtkBuildable interface allows
 * to specify the model columns with a <columns> element that may contain
 * multiple <column> elements, each specifying one model column. The “type”
 * attribute specifies the data type for the column.
 * 
 * An example of a UI Definition fragment for a tree store:
 * |[
 * <object class="GtkTreeStore">
 * <columns>
 * <column type="gchararray"/>
 * <column type="gchararray"/>
 * <column type="gint"/>
 * </columns>
 * </object>
 * ]|
