[geotk] puzzle-gis lookup

[Thys Meintjes]

Thanks Johan - I'm messing with it like this, for now...:-)
@Override
    public void actionPerformed(ActionEvent e) {

        Collection<Radar> radars = (Collection<Radar>)
Lookup.getDefault().lookupAll(Radar.class);
        GISProject project = (GISProject)
OpenProjects.getDefault().getMainProject();
        for (MapContext context : project.getContexts()) {
            for (Radar radar : radars) {
                TargetMapLayer targetLayer = new
TargetMapLayer(radar.getTargetManager());
                context.layers().add(targetLayer);
                RadarLayer radarLayer = new RadarLayer(radar);
                context.layers().add(radarLayer);
            }
        }
    }

The auto map save mechanism of course now adds these "ephemeral" layers. But
I'll look into that during the day.

Thanks again.
