Suggestions regarding Causality

Thanks Arthur for your valuable feedback. I agree that section is long, but as it was the most fundamental principle to design a causal model, I wanted it to keep it elaborated. Hence your suggestion of adding a concise goal paragraph will help.

On your second point, if you read the last paragraph of the faithfulness axiom, you can see how I tried to link them. However since it's not explicitly clear, I will edit that section further to make it more precise. Will let you know once I am done with that.

thanks again Prithu
