Summary:
Using `react-docgen` to automatically generate docs for our UI components.
React-docgen parses the files in `components/ui` and using comments and flowtypes to generate structured information about the UI components.
For higher-order-components `react-docgen` is not able to get the information. As we are using HOC often as part of emotion's styled-components, I added a custom parser for HOCs. Using babel/parser I am parsing the components and using their doc-comments to generate the structured description.
Then, the description generated by react-docgen and my custom parser is used to generate markdown which is added to the `ui-components.md` file of our docs.
Plus: Added some styling around the documentation of props, mostly table styles.
