Use ng-src to get rid of console errors for interpolated img srcs
Update book detail page
Save current user as books user when add new book.
Add logic to find the book if it already exists in the database and add the user, otherwise, grab book info
Nest the get request in the delete request so that it will always happen after the delete request, I nested it in both the success and the error because I keep getting a 404 not acceptable error every time I delete something which I will ignore for now since the books are still successfully deleting
