Batch edit of the heading

At the moment is not possible to edit in a batch way an heading. You can create a new heading and you can delete the association of an heading from the related record (you cannot delete it from the database using the app MARCcat, but only running some procedures, of course if it is required by the library).

The function allows to edit an heading: this means that starting from the index I can edit the heading and the changes made on this heading will be reflected on all the associated records.
The function also allows to delete an heading starting from the index. But to delete an heading, it should be a 0 (= zero) heading (meaning it has no record associated with it).
