As a Visitor,
I should not be permitted to save a book review using a name
I've previously used to review a specific book.
As a Visitor,
When I visit a user's show page to see their reviews,
I see additional links to sort their reviews in the following ways:
- sort reviews by highest rating, then by descending date
- sort reivews by lowest rating, then by ascending date
As a Visitor,
When I visit the book index page,
In the Statistics area of the page,
I should also see three authors who have the highest-rated books
As a Developer
I will spend additional time on HTML layout and styling
to create a visually oustanding project
