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.
