I give up. I tried to find a place where to put such an option.
But I just don't�� have a clue how all that works. The interaction between
NewList, NewListModel, NewListAdapter, MorphicNewListAdapter and NewListRenderer.
If I add an "providesIcon" option to NewListAdapter, it does not work on an the lists used
in EyeInspector. If I add this option to MorphicNewListAdapter, it does not work for NewListExample.
I don't think I have to add a instvar, setter and getter to three different classes just to make this work.
