-Subject: model.uci: add add_to_set / remove_from_set
-
-Adds two functions to simplify working with UCI lists:
-
-- add_to_set, which ensures a given value will be present in a list, and
-- remove_from_set, which removes a value from list.
-
-I've called these methods "set" because they treat the list as a set,
-i.e. duplicated values will be removed. Also, order is not preserved.
