-- The tree interface used by GtkTreeView
-- 
-- The @GtkTreeModel@ interface defines a generic tree interface for
-- use by the @GtkTreeView@ widget. It is an abstract interface, and
-- 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 @GtkTreeView@ 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 using
-- the GType system (ie. @/G_TYPE_INT/@, @/GTK_TYPE_BUTTON/@, @/G_TYPE_POINTER/@,
-- etc). 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 @GtkTreeStore@ and the @GtkListStore@. 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 t'GI.Gtk.Structs.TreePath.TreePath' and
-- the t'GI.Gtk.Structs.TreeIter.TreeIter' (“iter” is short for iterator). Most of the
-- interface consists of operations on a t'GI.Gtk.Structs.TreeIter.TreeIter'.
-- 
-- A path 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. A t'GI.Gtk.Structs.TreePath.TreePath' can be converted into either an
-- array of unsigned integers or a string. The string form is a list
-- of numbers separated by a colon. Each number refers to the offset
-- at that level. Thus, the path @0@ refers to the root
-- node and the path @2:4@ refers to the fifth child of
-- the third node.
-- 
-- By contrast, a t'GI.Gtk.Structs.TreeIter.TreeIter' is a reference to a specific node on
-- a specific model. It is a generic struct 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
-- 'GI.Gtk.Interfaces.TreeModel.treeModelGetIter'. These iterators are the primary way
-- of accessing a model and are similar to the iterators used by
-- @GtkTextBuffer@. They are generally statically allocated on the
-- stack and only used for a short time. The model interface defines
-- a set of operations using them for navigating the model.
-- 
-- It is expected that models fill in the iterator with private data.
-- For example, the @GtkListStore@ model, which is internally a simple
-- linked list, stores a list node in one of the pointers. The
-- @GtkTreeModel@Sort stores an array and an offset in two of the
-- pointers. Additionally, there is an integer field. This field is
-- generally filled with a unique stamp per model. This stamp is for
-- catching errors resulting from using invalid iterators with a 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). The model is considered
-- to own all outstanding iterators and nothing needs to be done to
-- free them from the user’s point of view. Additionally, some models
-- guarantee that an iterator is valid for as long as the node it refers
-- to is valid (most notably the @GtkTreeStore@ and @GtkListStore@).
-- 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 'GI.Gtk.Flags.TreeModelFlagsItersPersist' flag was added to
-- indicate this behavior.
-- 
-- To help show some common operation of a model, some examples are
-- provided. The first example shows three ways of getting the iter at
-- the location @3:2:5@. While the first method shown is
-- easier, the second is much more common, as you often get paths from
-- callbacks.

-- 
-- The @GtkTreeModel@ interface contains two methods for reference
-- counting: 'GI.Gtk.Interfaces.TreeModel.treeModelRefNode' and 'GI.Gtk.Interfaces.TreeModel.treeModelUnrefNode'.
-- These two methods are optional to implement. The reference counting
-- is meant as a way for views to let models know when nodes are being
-- displayed. @GtkTreeView@ will take a reference on a node when it is
-- visible, which means the node is either in the toplevel or expanded.
-- Being displayed does not mean that the node is currently directly
-- visible to the user in the viewport. Based on this reference counting
-- scheme a caching model, for example, can decide whether or not to cache
-- a node based on the reference count. A file-system based model would
-- not want to keep the entire file hierarchy in memory, but just the
-- folders that are currently expanded in every current view.
-- 
-- When working with reference counting, the following rules must be taken
-- into account:
-- 
-- * Never take a reference on a node without owning a reference on its parent.
--   This means that all parent nodes of a referenced node must be referenced
--   as well.
-- * Outstanding references on a deleted node are not released. This is not
--   possible because the node has already been deleted by the time the
--   row-deleted signal is received.
-- * Models are not obligated to emit a signal on rows of which none of its
--   siblings are referenced. To phrase this differently, signals are only
--   required for levels in which nodes are referenced. For the root level
--   however, signals must be emitted at all times (however the root level
--   is always referenced when any view is attached).
