Render default component if not enrolled in ABTest

[mattrheault]

If I have an experiment that I want to show conditionally on some value, then I would assume that if a user is not enrolled, then they should see the children of the Default component.

EX: Here we should see the Default component render if shouldEnroll is false.

render() {
  const shouldEnroll = true || false;

  return(
    <ABTest experiment={experiment} on='foo' shouldEnroll={shouldEnroll}>
      <When value='bar'>
        {...}
      </When>
      <Default>
        {...}
      </Default>
    </ABTest>
  );
}

apart from adding that test, this looks good to me.

Also I should really finish setting up travis-ci for this...

Closing this. We talked it out and decided that shouldEnroll should be deprecated and abstracted away to the planout experiment/namespace class definition.
