Easy-user-input

Added test cases for `inputPath`

- Removed compatibility script and replaced it with `__input__.py` hacks
- This is easier to maintain as there is only one file to update method signatures in
- It also means that some python tools won't detect `easy_user_input.easy_user_input` as a module, even when it is

- Added pytest as a development dependency
- Added test cases for `inputYesNo`, `inputChoice`, and `inputStrictString`

Fixed improper import in compatibility script

Major change: renamed easy_user_input.py to eui.py

This means that `import easy_user_input.easy_user_input` is now `import easy_user_input.eui`

The same functions are still available in the easy_user_input.py file for compatibility, but this file will be removed altogether in a future release.

Updated README

Added debug message and properly updated version number
