Grant permission to Open Zeppelin to release derivative implementation on MIT license

[albertchon]

The Open Zeppelin team would like to include standard implementations of ERC-777 and ERC-820 in our repository https://github.com/OpenZeppelin/openzeppelin-solidity/. We are seeking permission to release a modified version of the implementation of the standards found in this ERC777 repo as well as the ERC820 repo https://github.com/jacquesd/eip820.

Could we get your permission to do this?

Hello, could you please provide the permission to use some of the files in this repo under MIT license ? My opinion is that only the interfaces are considered "derivative work" of this repo if used elsewhere, while other implementations are not a derivative work. Thanks.
