License and author documentation

[nuest]

(part of openjournals/joss-reviews#662)

The requirements for the software license are fulfilled, however as a reader I still find it useful to have a reference to the license and the authors in the README file. I suggest to add a short section to the end of the README.

You can also use that section in the README to clarify the involvement of the third author listed in paper.md (
Edmilson Freitas ) who did not contribute via GitHub (https://github.com/atmoschem/EmissV/graphs/contributors).

Hi @nuest
I added the short description of the license and the package

[nuest]

My apologies for being unclear, I think it is even better to not repeat legal terms, but just say "This project is published under the X license."

In you case

Thank you @nuest
