Submit Pin Input Values in a Form with a Hidden Input

In some cases you'll want to actually have your pin input in a form to handle submitting the values. What's awesome about our implementation is that it doesn't get in the way of adding functionality like this.

First we'll extend our state machine to focus the first input when we click on the input label. Then we'll wrap our Pin Input component in a form element and implement an onSubmit. We can submit values of the form by creating a hidden input and set it's values to the joined values of the other inputs.
