This factory loads external images and places them the stage.
This package has been modified from it's original usage,
so some of the naming conventions my seem odd.
The factory is initialized like this:

var factory:ExternalImageCreator = new ThumbnailCreator();

and new images are created like this:

item is an XML piece,
100 is the x location,
150 is the y location,
this is the parent
factory.addThumb(model,controller,item,100,150,this);
