Fpinpy

- Unit tests for IniConfigReader!
- readSection replaced by getSection using new SinglyLinkedList

v1.0.8 had type issues that were detected after running mypy on the module. These errors were fixed.

- Better unit test coverage and structure. Easy to add new tests in an organized fashion.
- Several functional list functions have been implemented in an imperative, pure Python way.
- See commits for functionality added to SinglyLinkedList.
- Still missing support for Result composition.

Built using virtual environment.

Added classifiers according to PEP 301.
