enable None file_paths for related_name
change default sorting of related names to a more natural
use str.splitlines() instead of split('\n'), which is better for non unix systems
some docstring improvements
no str cast on None for module paths
renaming should work now.
remove unnecessary assert
basic exctract refactoring (not working yet)
