Implement Object Oriented Programming concepts

[alec-kr]

Problem

Currently, we have no object-oriented programming (OOP) principles employed in the project. This will make it difficult when trying to implement new features later during the development of the package. There will also be increased complexity as we continue to develop the project without any OOP concepts.

Solution

Classes should be implemented in each of the function files.
Example: race_schedule.py can contain a class RaceSchedule, that accepts JSON data and processes it.

This change will potentially reduce the difficulty during debugging. The readability of the code will also be increased, thus making it easier for new developers to begin contributing.
