After you compile JS, you get a set of class files. To load them as 
classes you need to create ClassLoader and define classes there. You can 
either create you own or use Context.createClassLoader which gives you 
an instance of GeneratedClassLoader where you can call 
GeneratedClassLoader.defineClass to load the classes.
