Testing the components

Every core component, and preferably all other components, should have accompanying Storybook stories. This allows team members to easily know what components exist already and understand what still needs to be developed. If a component has multiple variants, these should all be included within the same Storybook collection. Additionally, any required props for the component should be displayed in the 'Controls' tab within Storybook.

All the stories can be viewed by running `npm run storybook` and by opening `http://localhost:6006/` in your browser of choice.
