/** The base class for every note editors.

  *  The Basket class calls NoteEditor::editNoteContent() with the NoteContent to edit.
  *  This method create the good child NoteEditor depending
  *  on the note content type and return it to the Basket.
  *  This custom NoteEditor have two choices regarding what to do in its constructor:
  *   - Display a dialog and then call cancel() if the user canceled the dialog;
  *   - Create an inline editor and call setInlineEditor() with that editor as parameter.
  *     When the user exit the edition, validate() is called by the Basket.
  *     You should then call setEmpty() is the user cleared the content.
  *  The custom editor SHOULD call the NoteEditor constructor.
  *  If the user cleared the content OR if the user canceled the dialog whereas he/she
  *  JUST ADDED the note, then the note will be deleted by the Basket.
