Construct a new instance of the library. This is a hard-coded
example. In a real app, the books and publishers would come
from a database.
Publisher oreilly = new Publisher("oreilly", "O'Reilly",
"101 Morris Street", "Sebastopol", "CA", "95472");
this.publishers.add(oreilly);
this.books.add(new Book(oreilly, "XML Pocket Reference", 1,
"Robert Eckstein", "1-56592-709-5", 10, 1999));
this.books.add(new Book(oreilly, "Java and XML", 1,
"Brett McLaughlin", "0-596-00016-2", 6, 2000));
