-- modul list - 2016-03-16
-- main functions:
-- list - accepts two required parameters and some optional parameters. it returns a list.
-- count - accepts two required parameters and returns the number of list items.
-- category - accepts four parameters and returns categories.
-- error handling:
-- factory
-- message
-- analyze
-- helping functions:
-- trim - removes spaces on the begin and the end of a string
-- delink - delinks a link, so it returns [[Ulo]] or [[Artikolo|Ulo]] like Ulo.
-- link - links a text, if it isn't a link already, else it returns the text without a change.
-- template - puts a template into the module or if you add the name of a template only, it parses the template
-- listitem - creats a list item depending of the given value of the parameter mode
-- spanitem - creats a span item
-- basic texts for error messages
