/**
 * Article's page
 *
 * This page is used to see an article (or story) and is mainly called from
 * the module's index page.
 *
 * If no story Id has been placed on the URL or if the story is not yet published
 * then the page will redirect user to the module's index.
 * If the user does not have the permissions to see the article, he is also redirected
 * to the module's index page but with a error message saying :
 *     "Sorry, you don't have the permission to access this area"
 *
 * Each time a page is seen, and only if we are on the first page, its counter of hits is
 * updated
 *
 * Each file(s) attached to the article is visible at the bottom of the article and can
 * be downloaded
 *

 * - To create more than one page in your story, use the tag [pagebreak]

 *   of the article, "Edit & Delete"
