Question: package.lock and yarn.lock both exist

[docrinehart]

@ryanlanciaux Is the intent to support folks using either npm OR yarn? In my experience, we typically dictate one or the other for a project and that is the one you use for the project. I ran into some issues running npm install and I'm wondering if that's because I should have used yarn install.

Could you clarify for me if both are intended to exist or which package manager you'd prefer to keep around?

Update: PR #849 removed the yarn.lock file, but the question stands. Both were being used until that last merge, so I'd like to see what your preference is.
