/**
 * This view helper overrides the default one from Extbase, to include
 * everything the extension needs to work properly.
 *
 * The only difference in Fluid is that the attribute "name" becomes mandatory,
 * and must be the exact same name as the form parameter in the controller
 * action called when the form is submitted. For instance, if your action looks
 * like this: `public function submitAction(ExampleForm $exampleForm) {...}`,
 * then the "name" attribute of this view helper must be "exampleForm".
 *
 * Thanks to the information of the form, the following things are automatically
 * handled in this view helper:
 *
 * - Class
 *   A custom class may be added to the form DOM element. If the TypoScript
 *   configuration "settings.defaultClass" is set for this form, then the given
 *   class will be added to the form element.
 *
 * - JavaScript
 *   A block of JavaScript is built from scratch, which will initialize the
 *   form, add validation rules to the fields, and handle activation of the
 *   fields validation.
 *
 * - Data attributes
 *   To help integrators customize every aspect they need in CSS, every useful
 *   information is put in data attributes in the form DOM element. For example,
 *   you can know in real time if the field "email" is valid if the form has the
 *   attribute "fz-valid-email"
 *
 * - CSS
 *   A block of CSS is built from scratch, which will handle the fields display,
 *   depending on their activation property.
