+# 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 one string 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.
