Detailed Description

List_Model Abstract Widget.

A list_model is an abstract widget that's used with various viewer widgets that display the list_model's data. The list_model data is stored in rows that have a specified number of columns. Each column contains the same type of data. The list_model stores flat data, so there is no hierarchical structure as would exist in a tree.
