[Dune] Dune license

[Christian Engwer]

Dear Yimin,

the license has the same implications as LGPL, but is compatible with template code.

This means, you are allowed to use a license of your choice for any code built ontop of DUNE, but modifications of the DUNE code need to be published under the same license.

Still we encourage you to publish your code under an open source license, as we believe that scientific progress needs freedom.

Best
Christian
