Fix #28 refactored remote Llama

[Claire863]

Refactoring :

• File name (remote_llama.py instead of remotellama.py
• Class name (Llama instead of LlamaInterface)
• Class methods (static methods instead of standard methods)
• Document on url = "http://chaostree.xyz:3002/" in Class Llama

[Claire863]

Added Cameron as reviewer as he has been working on the LLama Class (or LLamaInterface)

Agreed we shouldn't mention Ollama.

It was good for me to understand how we 'accessed' Llama models, but it doesn't add anything to the core of the project and its maintainability.

Docstrings are updated.
