\class QtListModelInterface
\brief provides the abstract interface for list models.
\omit
A QtListWidgetNG is backed by four classes, a list controller
(QtListController) and a model. While QtListController is responsible for
handling all user input and model changes, QtListModelInterface is
responsible for displaying items on the list.
\endomit
QtListModelInterface provides an abstract interface for list model classes.
Each individual list item is referenced using an index, in the form of an
integer. Each item has multiple data roles, as specified by
Qt::DataRoles). Data can be requested using the data() method.
