/** Typedefed as TreeModel::ColumnRecord.
 * Keeps a record of @link TreeModelColumn TreeModelColumns@endlink.
 * @ingroup TreeView
 * ColumnRecord objects are used to setup a new instance of a TreeModel
 * (or rather, a new instance of an implementation of the model, such as Gtk::ListStore
 * or Gtk::TreeStore).  It is convenient to do that by deriving from
 * TreeModel::ColumnRecord:
 * @code
 * class MyModelColumns : public Gtk::TreeModel::ColumnRecord
 * {
 * public:
 *   Gtk::TreeModelColumn<Glib::ustring>                filename;
 *   Gtk::TreeModelColumn<Glib::ustring>                description;
 *   Gtk::TreeModelColumn< Glib::RefPtr<Gdk::Pixbuf> >  thumbnail;
 *
 *   MyModelColumns() { add(filename); add(description); add(thumbnail); }
 * };
 * @endcode
 *
 * Whether or not you derive your own ColumnRecord, you need to add the
 * @link TreeModelColumn TreeModelColumns@endlink to the ColumnRecord with the
 * add() method.
 *
 * A ColumnRecord instance, such as an instance of @c MyModelColumns should then
 * be passed to ListStore::create() or TreeStore::create().
 * The @link TreeModelColumn TreeModelColumns@endlink, such as the members
 * @c filename, @c description and @c thumbnail can then be used with Gtk::TreeRow::operator[]()
 * to specify the column you're interested in.
 *
 * Neither TreeModel::ColumnRecord nor the
 * @link TreeModelColumn TreeModelColumns@endlink contain any real data --
 * they merely describe what C++ type is stored in which column
 * of a TreeModel, and save you from having to repeat that type information in several places.
 *
 * Thus TreeModel::ColumnRecord can be made a singleton (as long as you make
 * sure it's instantiated after Gtk::Main), even when creating multiple models
 * from it.
