Restructured and modularized code

[AdityaKane2001]

@sradc

As discussed I have modularized the code in a way I think is best. Please take a look at the structure and let me know if you think there need to be any changes. All tests are passing.

Hey, sorry for the delay. Looks like a good start. Can you:

• Format the files with black, black --line-length 92
• Have this as the header of the files:

@sradc

Done!
Since I'll be contributing a ton to the repo, could you please make me a collaborator? It will make it easy to handle things, I can keep a branch for myself.

[sradc]

@AdityaKane2001, will do.

PR lgtm, but README.ipynb seems to be corrupted. Do you also get this issue, and can you revert the notebook so it's non-corrupted?

[AdityaKane2001]

@sradc

Restored the notebook.

Thanks for the invitation!

[sradc]

lgtm. I ran the tests locally they pass. Thanks for adding the license + formatting. I was never 100% sure about the modularisation, but happy to go with it and see how it works out.

[AdityaKane2001]

@sradc

I see. Thanks for merging!

Let me know what's the upcoming agenda.

Edit: I'd just need a few days to read up the code. I'm not yet completely familiar with the code, so I'll just go through it and then I'll start any new tasks. Sounds good?

@AdityaKane2001, np!

No problem, let me know if you have any questions. I think the documentation could be improved, and I do plan to write a more tutorial style guide to the implementation at some point.

The stuff on this todo list still looks good, and I'm happy to hear other ideas too.
