Don't Merge! Added type hints and docstrings (811 lines)

[rhiza-fr]

Hiya, and thanks for this elegant and powerfull project implemented with extraordinary brevity.

For a friendlier developer experience, this fork adds type hints and docstrings throughout __init__.py

This makes autocompletion and inline help available without having to refer to the docs.

Alas, it also forced named parameters to be strictly conformant to the base classes, so this led to many doc and example modifications.... ho hum. Otherwise functionality is unaltered.

I conformed to __init__.py's naming: shared, prep_res and exec_res. This may be too brief for some - I see in some examples and doc you used shared_storage, prep_result and exec_result which are more self evident.

Respectfully,

[rhiza-fr]

Responds to issues #61 and #49 .

Very cool! There was already a merged PR for type hint btw:
#86

Thank you, we should use the codebase with docstring and newlines as the base.
maybe you can add a utility to minify it
And contribute it as the marketing version. Hope the pocketflow owner would consider this compromise.
