Updated the guides for having a distinct has_many through at the database level
The current example
add_index :person_articles, :article, unique: true
Does not work, the `:article` column does not exist as it will be
a join table (based on the prior example) so should use :article_id
The documentation seems to suggest that it will allow an article to
be added only once to a person via the join table, what actually
occurs is that it only allows the article to be added to one person,
at which point it should be a `belongs_to` association.
Also changed the new example to use readings based on the prior example
