#- heritate from this class and you'll get all made interactivity for same steps.
#- for this you need to provide
#- - ask_from_listW(o, title, messages, arrayref, default) returns one string of arrayref
#- - ask_many_from_listW(o, title, messages, arrayref, arrayref2) returns many strings of arrayref
#-
#- where
#- - o is the object
#- - title is a string
#- - messages is an refarray of strings
#- - default is an optional string (default is in arrayref)
#- - arrayref is an arrayref of strings
#- - arrayref2 contains booleans telling the default state,
#-
#- ask_from_list and ask_from_list_ are wrappers around ask_from_biglist and ask_from_smalllist
#-
#- ask_from_list_ just translate arrayref before calling ask_from_list and untranslate the result
#-
#- ask_from_listW should handle differently small lists and big ones.
