- I wrote this on the train after a long day with a heavy head cold. I haven't run it, 
but regardless of likely errors I think it expresses the design well enough.

- Segment and ConditionSet look close to identical, but that's likely due to the simplified
nature of the outline you provided

- I don't like attaching components to classes unless they're `js-`, as it's coupling 
your styling and behaviour layers. We excelusively use data attributes for JS-DOM coupling 
and I've quickly grown fond of the approach.
