ListService for GraphService<WindupVertexListModel>

WindupVertexListModel is used quite often.

A convenience ListService would be nice, to shorten this
{{
GraphService<WindupVertexListModel> listService = new GraphService<WindupVertexListModel>(context, WindupVertexListModel.class);

WindupVertexListModel sessionBeans = listService.create();
for (EjbSessionBeanModel sb : ejbDescriptor.getEjbSessionBeans())

{ sessionBeans.addItem(sb); }

}}

to this

ListService listService = new ListService(context).wrap(ejbDescriptor.getEjbSessionBeans())
