Also added some REST API sample reference text files and fixed a typo there where the endpoint was using "book" where it should be "books".
Updated SQL file so that the existing reviews are reflected in the Book table fields (review_score, number_of_reviews).
Fixed a part of AddressService where I forgot to use/call a function I created in order to check if there is an existing address with the same values for "street" and "zip".
