Add a license

Just went through [https://github.com/renproject](https://github.com/renproject) and a good critical chunk has no license. Ex: Shamir, Mercury, or Darknode. ​ Could you please add an open-source software license to your code? Check out: [https://choosealicense.com/](https://choosealicense.com/) Without a license, as it is, all your code is under copyright, which means that \[no one can copy, distribute or modify it\]([https://choosealicense.com/no-permission/](https://choosealicense.com/no-permission/)). Is that what you intent? ​ \> Making the entire codebase public immediately opens up RenVM to be exploited via zero-day vulnerabilities. - [https://docs.renproject.io/darknodes/community/renvm-open-source-transparency-plan](https://docs.renproject.io/darknodes/community/renvm-open-source-transparency-plan) Security by obscurity is a broken model.
