License information

[lirantzafri]

I've started using batch_job and it works great! I was wondering if you could add a license information to the repository though, which would make it easier to use.
It should be pretty straightforward, as described in the following:

MIT License would be nice, but it's obviously up to you. You can choose a license using:

Thanks for the request. I just added the MIT license.
