[Ves] Extending the App

[Eduardo Poyart]

Hello,

I extended vesKiwiViewerApp with my own subclass ViewerApp. I also needed
to create a new representation, which I called ImageWidgetRepresentation,
extending from vesKiwiWidgetRepresentation.

I wrote a custom load routine in ViewerApp, and now I need to add the data
to Internal, with something like:

this->Internal->DataRepresentations.push_back(rep);

However this can't be done since vesKiwiViewerApp.Internal is private. What
is the correct design pattern in this case?

Thanks
Eduardo
