By grammar, this is where things are headed:

		firstName = "Brenda";
		lastName = "Lee";

but maybe I'm not using Scanner correctly because guests.get(0) is the 
whole line, whereas I expected useDelimiter() to break it into smaller 
pieces based on using a comma as the delimiter.  I'll re-read the Sun 
tutorial, http://java.sun.com/docs/books/tutorial/essential/io/
scanning.html, but that's what I thought they were doing.
