closes #500

Or at least a big part of it. There are lots of nuances here that aren't covered that will be impossible to do, unless we incorporate https://github.com/projectwallace/format-css to format each node before adding it to the collections. That's a trade-off I'm not willing to make at his point, but might revisit later on.
