 * classe de base `profile_manager` qui permet de gérer des profils
+* class Tool permettant d'appliquer un traitement à une valeur scalaire
+  * ArrayTool permet d'appliquer les traitement à tous les éléments du tableau
+  * les traitements sont une suite d'opérations à faire, ou de filtres à
+    appliquer, qui ne sont appliqués que lors du parcours effectif de la liste
+  * exemple
+    ```php
+    $result = ArrayTool::with($source)
+      ->filterKey("key")
+      ->filter("value")
+      ->add("value", "key")
+      ->addAll($iterable)
+      ->all();
+    ```
+    déterminer le genre de traitements que l'on peut offrir
