Add MIT License

Thanks for this excellent implementation! Would it be possible to add an MIT license on the repo? At this website you can past your repo URL and it will automatically create the Pull Request to add the license file: https://choosealicense.com/licenses/mit/.

Hi! I’ve just opened a pull request to add the MIT license file, which should resolve #3. Let me know if you need any changes or if it looks good to merge. Thanks for the great project!
