Add a permissive license to the project

[morganestes]

I've used this project to learn nodejs development with Heroku, and would like to release the code I've written under the MIT and GPL licenses, but since there's not a license declared here, that's not possible.

Would you be willing to release this under the MIT license (or GPL, or other permissive license) so anyone who forks it for learning can also release the work their work easily?
