// Requires Input behavior
//
// When called on a form with input fields with the `required` attribute, the
// form's submit button will be disabled until all required fields have values.
//
/*= require extensions/jquery */
//
// ### Example Markup
//
// <form class="js-requires-input">
// <input type="text" required="required">
// <input type="submit" value="Submit">
// </form>
//
