/**
* Action to edit a post
*
* When called via GET, it shows an edit form
* including the current data of the Post.

* <li>id: Id of the post (via HTTP POST and GET)</li>
* <li>title: Title of the post (via HTTP POST)</li>
* <li>content: Content of the post (via HTTP POST)</li>
* </ul>
*
* The views are:
* <ul>
* <li>posts/edit: If this action is reached via HTTP GET (via include)</li>
* <li>posts/index: If post was successfully edited (via redirect)</li>
* <li>posts/edit: If validation fails (via include). Includes these view variables:</li>
* <ul>
* <li>post: The current Post instance, empty or being added (but not validated)</li>
* <li>errors: Array including per-field validation errors</li>
* </ul>
* </ul>
* @throws Exception if no id was provided
* @throws Exception if no user is in session
* @throws Exception if there is not any post with the provided id
* @throws Exception if the current logged user is not the author of the post
* @return void
