    -- 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).
