Final

To solve this problem I am going to:
1. Add a comments view to my post.php page.
2. Add a comments table to my database, as described below.
3. Fetch the comments for every page.
4. If logged in, show comment form.
5. Create comment submission logic.

comment_title VARCHAR(50) NOT NULL
comment_author VARCHAR(50) NOT NULL
comment_text VARCHAR(2000) NOT NULL
comment_date DATE NOT NULL
