Addition of the Code of Conduct & the Contributing guideline

[FahimFBA]

Your project is pretty decent, but some addition to it would make it even better. Such as, If you add the Code of Conduct to the root branch and also add a Contribution guideline, then that would make the project more engaging.

If you want, then I can submit a PR including the Code of Conduct. In that case, I need the contact address (email) to enlist that to the Code of Conduct file.
