Built Author and Books classes in models.py and edited admin.py of bookshelf app

+Created Author and Books classes. The Author class contains fields to keep track of the author's first and last name, age, nationality, and bio. The Books class contains fields to keep track of the book's title, author, publisher, publishing year, ISBN, and blurb.
+The admin.py file was edited to create admin panels for the 2 classes in models.py
- haven't removed the placeholder for views.py under bookshelf. This will be edited later on.
