[forge-dev] Hello World Template

If I do the following, it doesn't work :
ResourceFactory resourceFactory = furnace.getAddonRegistry(ResourceFactory.
*class*).get();
TemplateProcessorFactory factory =
furnace.getAddonRegistry(TemplateProcessorFactory.*class*).get();
That because the method getAddonRegistry takes a AddonRepository.
Any idea ?
