place_component activates the Tool to manually place a
ComponentInstance via GUI
add_instance explicitly places one via Ruby
You probably don't want to do both?
#status=model.place_component(compdef)
need to create trans before you can use it! This creates an identity,
which adds the instance at the model origin
trans=Geom::Transformation.new
Sketchup.active_model.active_entities.add_instance(compdef, trans)

Also, you should isolate your code in a module so that the method does not go into the global namespace.
