WIP - Testing on Notebooks - Refactor COT - Remove inheritance from predict and convert it to module.

[ammirsm]

What is the change?

• I have converted the COT to use the Predict instead of inheritance of predict and make it as module.

Why the change is important?

• We are in refactor phase that we wanna clean up stuffs and one of the part is to make sure anything is not inheriting from predict.

How to test?

• Run tests in the tests/ folder with pytest.
• Run notebooks to make sure they are fine.

Thanks so much @ammirsm — will this break saved checkpoints

Btw for the record, for this change I think the output of the following pieces of code may change, e.g. in ScoNe:

https://github.com/stanfordnlp/dspy/blob/main/examples/nli/scone/scone.ipynb

 cot_fewshot.save("scone-cot_fewshot-turbo-gpt4-demos.json")


cot_fewshot = ScoNeCoT()
cot_fewshot.load("scone-cot_fewshot-turbo-gpt4-demos.json")

Nothing special about scone, just basic .save() and .load() after a BootstrapFewShot run of any kind
