Code converted into Object Oriented Approach

[emekgozluklu]

Since the nested function structure is not useful, I changed the code using Object Oriented Approach. It provides:

• Other people can import and use this class with their datasets
• No need to pass attributes as arguments. Used class attributes.
• Methods of the class can be runned seperately for observations.
• The code is more clean, readable and documentable.

Missing requirements.txt and .gitignore files are added.
