The Travis failure is not due to changes in this PR.

This is an incremental improvement but dances around the goal of idiomatic code style. For instance it doesn’t take any steps towards addressing #65. I don’t see harm in landing this but I think some of the larger architectural patterns still need to be dealt with. Moving towards idiomatic code, direct object creation, and immutable instances requires eliminating the setter functions and using class get functions. Personally I think it would be worth exploring that approach.

Yes, I'd like to get there too, but I don't want to change the whole codebase by renaming methods at this point.

I'd like to merge this incremental improvement and make small PRs. Right now I can't even make simple changes due to Travis configs and DCO checks which makes things painful.

@grant you should rebase from master to pull in the Travis-CI code coverage fix. That will re-run the tests and you'll see a successful build.

I think the PR Quality Review tool is actually wrong here. It's saying an object is a block.

@grant I agree - the Codacy rule seems broken.
