- updated entities to auto id generation
- implemented basic search functionality for books.  Can now search for
books by regular expression on title, author and publisher.  Only shows
the titles of matching books; still a lot of work to do there, but I
consider getting a working list of books a win.  Reference
EntitiesService.searchBooks() for a template for future searches
- added a bunch of views/backend functionality for them that don't work
yet, particularly in relation to the dml's
