* Retain almost all ratings ratings
* Exception: AbstractTextCellDatabindingEditingSupport, whose
  setupFieldAssist() method was removed since
   * it would have introduced a dependency to another package in
     base.ui only because is "FieldAssist" class was referenced in
     the method *comment*.
   * However, this method is only used very rarely and users of the
     class setup up their field assist in createCellEditor() instead.

* Add a TreeViewer that constructs a DynamicTreeViewer whose UI provider
  uses the methods and kernel services for IHierarchicElements and
  NamedElements.
* The Viewer uses a composition principle where a client must provide
  TreeView (JavaFX), a root element (AF3), and a content provider that
  selects the elements to be displayed.
* Add two basic content providers that a) list all children below the
  given root element and b) list all children of a given type.
