First patch

MInd to close the issue inside the commit via a Closes xxxx reference?
Like coala I also like tags in commits ;) I think

LineModel: Rename connections() to edges()

as shortlog would fit pretty well.

I'm not so strict with shortlogs having only 50 chars max btw, I allow 72 like in the commit body. Usually you can write way better shortlogs if you have more space than 50 chars, especially when using tags ;)
