The InspectorProperty generic class should provide a clear public interface. Some method are public, when they should not.

For instance, a setValue() called from the InspectorController or the InfoPanelController need to call the following sequence to set a value:
                    controllerClassEditor.setUpdateFromModel(true);
                    controllerClassEditor.setValue(className);
                    controllerClassEditor.setUpdateFromModel(false);
We should have 2 methods, one for an external usage that include the code above, and another one for the editor usage.
