This plugin is used to map isbn/editor with collection.
It need :
  in thesaurus, a category named EDITORS
  in this category, datas must be entered like following :
  isbn separator editor separator collection.
  for example :
  2204 -- Cerf -- Cogitatio fidei
  2204 -- Cerf -- Le Magistère de l'Eglise
  2204 -- Cerf -- Lectio divina
  2204 -- Cerf -- Lire la Bible
  2204 -- Cerf -- Pour lire
  2204 -- Cerf -- Sources chrétiennes

  when the user clic on ... on 225a line, the popup shows the list of collections from the selected editor
  if the biblio has no isbn, then the search if done on editor only
  If the biblio ha an isbn, the search is done on isbn and editor. It's faster.
