Add contributors guidelines and privacy policy

[HarryHeights]

Hello, I'm Harry. I engage in creating documents for open source projects. It's part of my contribution to helping open source projects. One of the documents I engage in creating is a privacy policy. The privacy policy will give details about user information collection, use and security. I really don't know if you externally collect user information, but, if you don't, it's good to let end users know via a privacy policy. Contributor's guidelines is also an important document that will help prospective collaborators contribute easily to your project.

I'll love to hear your thoughts on this.
