This function retrieves the model that provides data to a given widget.
The model that is returned will implement the interface for the given
class id. To illustrate, a widget that displays television signals might
get its data from an HDTV model, and as such could retrieve a pointer to
the appropriate model interface by calling IWidget_GetModel(), passing in
a pointer to the "television widget", and the class ID of the HDTV model
interface. The function would then return a reference to the appropriate
model interface used to source the television widget.
