* - 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
