Stemming & Lemmatization

With this version, I aim to create a fully-functional stemming and lemmatization toolkit to add into the instance.
I aim to avoid using third-party code libraries, such as PyTorch and NLTK, as this is only a hobby project at heart, for me to learn with.
Perhaps we might use a bit of numpy... or maybe PyTorch, who knows, depends...

As a bonus, I asked ChatGPT to write me a highly simplified Transformers script, which is found in the 'Experimental' directory :) have fun
