Resources: Data Mixed into Code
Resource data files can be of any format you want
In our example, the CodeFace.dir resource is a simple property file 
	lewis.gif = Jack
	belloc.gif = Hilaire
	tolkien.gif = J.R.R.
	macdonld.gif = George
The property file points the program to the
images it needs
The I18N API supports localization via higher-level classes like PropertyResourceBundle
