/** This class defines a generic tree interface for use by the Gtk::TreeView widget.
 * @ingroup TreeView
 *
 * It is is designed to be usable with any appropriate data structure. The
 * programmer just has to implement this interface on their own data type for
 * it to be viewable by a Gtk::TreeView widget.
 *
 * The model is represented as a hierarchical tree of strongly-typed, columned
 * data. In other words, the model can be seen as a tree where every node has
 * different values depending on which column is being queried.  The type of
 * data found in a column is determined by TreeModel::Column<> templates.
 * The types are homogeneous per column across all nodes. It is important to note that this
 * interface only provides a way of examining a model and observing changes.
 * The implementation of each individual model decides how and if changes are
 * made.
 *
 * In order to make life simpler for programmers who do not need to write their
 * own specialized model, two generic models are provided - the Gtk::TreeStore
 * and the Gtk::ListStore. To use these, the developer simply pushes data into
 * these models as necessary. These models provide the data structure as well
 * as all appropriate tree interfaces. As a result, implementing drag and drop,
 * sorting, and storing data is trivial. For the vast majority of trees and
 * lists, these two models are sufficient.
 *
 * Models are accessed on a node/column level of granularity. One can query for
 * the value of a model at a certain node and a certain column on that node.
 * There are two structures used to reference a particular node in a model.
 * They are the @link Gtk::TreePath Path@endlink and the iterator. Most of the interface consists of
 * operations on an @link Gtk::TreeIter iterator@endlink.
 *
 * A @link Gtk::TreePath Gtk::TreeModel::Path@endlink is essentially a potential node. It is a location on a model that may
 * or may not actually correspond to a node on a specific model.
 *
 * By contrast, an @link Gtk::TreeIter Gtk::TreeModel::iterator@endlink  is a reference to a specific node on a specific
 * model. One can convert a path to an @link Gtk::TreeIter iterator@endlink 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 @link Gtk::TreeRowReference RowReference@endlink is also useful, because it remains
 * valid as long as there is an existing row pointed to by it's path. You can convert between RowReferences and iterators and @link Gtk::TreePath Path@endlink s.
