The licence is GPLv3+ because the code is closely influenced by 
igraph, which is GPLv3-licensed. It's not like there's 
copy-pasting, but it's not clean-room either, so offering a 
permissive licence might put users in an invidious situation if 
the igraph authors chose to make an issue of it. Unlikely, but 
better safe than sorry.

If anyone wants to use it in a commercial application the best 
thing probably to let me know and I can discuss with the igraph 
authors. I will probably do so anyway once the library is more 
feature-complete, less out of concern for commercial apps than in 
order not to be incompatible with other free licenses.
