Concept

Every tag consists of a tag name and options. The Tag class parses a string or a Line that contains a tag and splits up the name, the options and it's values.
Now you can search for options and their values and manipilate them.
Then you can rebuilt the tag with the rebuilt_tag() function and get the new tag with the get_tag() function.
