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 Gtk::TreePath and the Gtk::TreeIter. Most of the interface consists of operations on a Gtk::TreeIter.
-Models are composed of columns that contain the same data type, and rows that hold each set of data. Each model column can hold a single type of data. A tree model column should not be confused with a tree view column, which is composed of a single header but may be rendered with data from multiple model columns.
+Models are composed of columns that contain the same data type, and rows that hold the entire heterogeneous set of data for a row. On the other hand each model column can hold a single type of data (note that rows contain heterogeneous while columns homogeneous data types). A tree model column should not be confused with a tree view column, which is composed of a single header but may be rendered with data from multiple model columns.
