// In order to offer STL-like iterator functionality, we cannot wrap
// GtkTreeIter directly. Most GTK+ functions that operate on GtkTreeIter
// are virtual functions in GtkTreeModel. Therefore, the C++ TreeIter
// must store a pointer to the Gtk::TreeModel to which it belongs.
//
// Another problem, which is much worse, is that the GTK+ tree iterator
// doesn't support the STL-style half-open interval [begin,end). Instead,
// it uses a [first,last] interval, and functions return FALSE to indicate
// the end was reached. Also, some functions accept a NULL GtkTreeIter*,
// which will be interpreted as the end() iterator.
//
// Most of the immense complexity in the Gtk::TreeIter implementation is
// needed for proper emulation of [begin,end) intervals. Unfortunately,
// it's not even possible to encapsulate everything in the TreeIter
// class. Almost all wrapper methods dealing with GtkTreeIter must be
// carefully implemented by hand.

/** Typedefed as TreeModel::iterator and TreeModel::const_iterator.
 *
 * A Gtk::TreeModel::iterator is a reference to a specific node on a specific model.
 * It is a generic structure with an integer and three generic pointers.
 * These are filled in by the model in a model-specific way.
 *
 * One can convert a path to an iterator by calling Gtk::TreeModel::get_iter().
 *
 * These iterators are the primary way of accessing a model and are similar to the iterators
 * used by Gtk::TextBuffer. The model interface defines a set of operations
 * using them for navigating the model.
 *
 * The lifecycle of an iterator can be a little confusing at first. Iterators
 * are expected to always be valid for as long as the model is unchanged (and
 * doesn't emit a signal).
 * Additionally, some models guarantee that an iterator is valid for as
 * long as the node it refers to is valid (most notably the Gtk::TreeStore and
 * Gtk::ListStore).
 *
 * One can convert an iterator to a TreeRow or TreeConstRow, as appropriate, by
 * dereferencing it via TreeIter::operator*() or TreeIter::operator->(). The row
 * classes can give nicer syntax by avoiding repeatedly dereferencing iterators.
 * But see the warning re: reference safety in the doc of TreeIter::operator*().
 *
 * Although generally uninteresting, as one always has to
 * allow for the case where iterators do not persist beyond a signal, some very
 * important performance enhancements were made in the sort model. As a result,
 * the Gtk::TreeModel::Flags::ITERS_PERSIST flag was added to indicate this behaviour -
 * see Gtk::TreeModel::get_flags().

 * @tparam T TreeRow for an iterator, TreeConstRow for a const_iterator.
