/**
 * Helper class to manage 'blocks' of HTML pieces that are parts of a page and contain some list of cmdb objects
 *
 * 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
