Exercise: Google Books Client

Use Google's Books API to search for books in the catalog service:

1. Implement a component GoogleBooksClient that invokes the volume's list method (see API Reference) with appropriate query parameters (see API Guide)
2. Implement classes corresponding to the list method's response (see API Reference) and convert the returned objects into Book objects
3. In the catalog service update the following methods:
   • findBook searches the book in Google's Book API if it is not found in the local database
   • searchBooks returns all matching books of the local database and Google's Book API (without duplicates)
   (Books from Google's Book API that do not have an isbn, title, authors, publisher, or price are ignored.)
