  * Each block is actually rendered as a <div></div> tag that can be rendered synchronously
  * or as a piece of Javascript/JQuery/Ajax that will get its content from another page (ajax.render.php).
- * The list of cmdbObjects to be displayed into the block is defined by a filter
- * Right now the type of display is either: list, count, bare_details, details, csv, modify or search
- * - list produces a table listing the objects
- * - count produces a paragraphs with a sentence saying 'cont' objects found
- * - bare_details displays just the details of the attributes of the object  (best if only one)
- * - details display the full details of each object found using its template (best if only one)
- * - csv displays a textarea with the CSV export of the list of objects 
- * - modify displays the form to modify an object (best if only one)
- * - search displays a search form with the criteria of the filter set
