Added OrdinalClass

Added the "OrdinalScale" class in the core.py file. However, I modified the issues requesr slightly, so that the "statistics" and "distribution" class variables are instead set using class functions that call the respectively called functions

Hi @imrannasrullah ,

For me, it's ok, thanks for the methods - I wonder If they will persist, but at this moment, we let them be there ;) Two more things:

1. Could you create a simple docstring below class name with the list of Parameters and Attributes following numpy-style docs: https://github.com/hs3city/ordinal-scale-stats-py/blob/main/docs/dev-docstrings.md

2. I will set you as a contributor to this block of code within a script (core.py), but I need to know if you want to use only your Github handle OR your Github handle + your name and surname? If the second option, then let me know your full name (like people here, on the top of a file: https://github.com/hs3city/ordinal-scale-stats-py/blob/main/src/allison_foster.py)

Thanks!

Appreciate it, but it's fine! I was testing out my ability for first-time contributions since I'm new to Git, so I just wanted to try a first-issue. The code that I've pulled worked wonderfully, so I think that's experience enough for me.

Thanks so much!
