Included Combination Modifiers

The following combination modifiers are included by default. If you'd like to expand this list, PRs are welcome!

Name	Description
`withOneOfBool`	Takes an array of property names and adds more combination with one of these props set to true. For example, if we had `[{ label: 'my button' }]`, `withOneOfBool(['small', 'big'])` will add `{ label: 'my button', small: true }` and `{ label: 'my button', big: true }`. See this story for a more detailed example.
