* Add a treeModelValueGet function.
This patch makes it possible to retrieve the content of a store using the
TreeModel interface, that is, by using predefined columns. The ColumnId
type had to be amended for that. I used the opportunity to move its
definition to the TreeModel module, where it belongs. As a consequence
the two functions in CustomStore whose name started with treeModel
have been renamed to customStoreGetRow and customStoreSetColumn since they
really only make sense on implementations of CustomStores. The original
names are no longer documented but still exported in order not to break
exisiting programs.

+-- A 'TreeModel' stores records of the same type. Each record is referred to
+-- as row, just like in a relational database. Defining how the information of
+-- a row is displayed can be done in two ways: If the widget displays data
+-- using 'Graphics.UI.Gtk.ModelView.CellRenderer.CellRenderer' or one of its
+-- derivatives, it is possible to state how a row is mapped to the attributes
+-- of a renderer using the
+-- 'Graphics.UI.Gtk.ModelView.CellLayout.cellLayoutSetAttributes' function.
+-- Some widgets do not use
+-- 'Graphics.UI.Gtk.ModelView.CellRenderer.CellRenderer's to display their
+-- data. In this case an extraction function can be defined that maps a row to
+-- one of a few basic types (like 'String's or 'Int's). This extraction
+-- function is associated with a 'ColumnId' using
+-- 'Graphics.UI.Gtk.ModelView.CustomStore.treeModelSetColumn'. The latter can
+-- be set in the widget for the property that should be set. The widget then
+-- uses the function 'treeModelGetValue' and the 'ColumnId' to extract the
+-- value from the model. As the name suggests, using 'ColumnId's creates a
+-- view of the data as if each row were divided into a well-defined set of
+-- columns, again, like a relational database.
