[Ves] Add other models to the scene

[Pat Marion]

Are you are using the vesKiwiViewerApp class?  And you are using
vesKiwiViewerApp::loadDataset(std::string filename) to load the skull
dataset?  If that's the case, then the problem you're having is that the
loadDataset() method calls this->resetScene() before loading the new data,
so each time you call it, it replaces the current scene.

What I recommend is that you subclass vesKiwiViewerApp so that you have
your own custom app class that can implement your app's behavior.  Then
write some methods like this:

class MyApp : public vesKiwiViewerApp
{
public:

void loadScene()
{
  vtkSmartPointer<vtkDataSet> skull = this->getSkull();
  vtkSmartPointer<vtkDataSet> pin = this->getPin();

  this->addRepresentationsForDataSet(skull);
  this->addRepresentationsForDataSet(pin);
}

vtkSmartPointer<vtkDataSet> getSkull()
{
  std::string filename = "/path/to/skull.vtp";
  vesKiwiDataLoader loader;
  return this->Internal->loader.loadDataset(filename);
}

vtkSmartPointer<vtkDataSet> getPin()
{
  std::string filename = "/path/to/pin.vtp";
  vesKiwiDataLoader loader;
  return this->Internal->loader.loadDataset(filename);
}

};
