Add missing license, add list of third-party requirements and licenses in case they differ #54
Description
As of Mar 24, 2017 our licensing policy for
- Software: permissive licenses (MIT or BSD) if possible
- Resources: CC-BY if possible.
"
There is an ongoing group-intern debate on whether source code (e.g., the JCoRe code we distribute via GitHub) must comply with the licenses of the employed libraries if those are not included in the distribution and instead only referenced as a maven dependency (that would mean that using the API in the source makes the the source a derivative) or the source code rather constitutes a work of its own and only building the project merges source and libraries (thus constituting a derivative).
"
Anyways, I would recommend setting the BSD-2 clause license now and a prominent note at the top of the REAMDE that third party libraries might have different licenses -- better: make a list of all the third-party dependencies and their licenses respectively.
