Survey
The main component that generates a Survey Result. The name is probably not ideal, I should have named this SurveyResultDetail or something similar.
It includes a number of internal components that I've chosen not to expose, however, these could be moved into their own module folder should they be reusable at a later stage.
Rating
Uses d3 to render a really basic control that shows <= 2 unfavourable and >= 4 favourable metrics.
Notes
Most of the components are composite React components and I prefer createClass over es6 classes.
I would also make greater use of stateless components if I had more leaf nodes, but it didn't really come up.
