+  # This parameter accepts anything responding to .call method
+  # and receiveing one parameter: obj_id.
+  #
+  # Thus it is possible to use a lambda like this:
+  # 
+  #   release_collector = lambda do |obj_id|
+  #     # ...
+  #   end
+  #
+  # or a class based implementation.
+  #
+  # It is expected that the release collector returns an Array
+  # of Hashes with the following format:
+  #
+  #   [
+  #     {
+  #       # this is a title for a group of objects
+  #       title: 'This title will be shown in the dialog',
+  #       # this is the list of objects presented underneath
+  #       objs: [
+  #         {
+  #           # the ID of the object to be released
+  #           id: 2001,
+  #           # "Title" of the object which will be displayed
+  #           title: 'Root',
+  #           # "Description" of the object, typically obj_class
+  #           description: 'RootObj',
+  #           # If true, then release checkbox will be checked
+  #           # i.e. without additional input from the user it will 
+  #           # get released automatically
+  #           checked: true
+  #         }

+  # Obviously it possible to define multiple groups and multiple

+  #
+  # It is recommended that custom implementations inherit
+  # or delegate to Fiona7::ReleaseCollector which is the
+  # default implementation.
