Formation API:

When you include the library in the DOM, it adds a Formation object to the window. There are a number of useful methods available on Formation:

• initForm() - Allow consumers of Formation to initialize forms that may be added to the DOM after auto-initialization of the DOM
• setDebug() - when set to true, will log messages, warnings, etc to the console
• getDebug() - get the status of debug
• registerRule() - register a new rule to make it available
• getValidityChangedEventName() - the defined event for when a form/element’s validation state changes

Some useful DOM navigation methods (see ./src/utilities/dom-navigation.js`):

• findCurrentFormByTarget() - Pass in any element and it will return the current Formation form
• findRequiredFields() - find all required fields for the supplied form element
• findSubmitButton() - find the submit button for the supplied form element
• findOptionalFields() - find all optional fields for the supplied form element
• getAllCheckboxesOrRadiosByName() - find all input elements in the current form with the same name as the supplied element
• getCheckboxOrRadioContainer() - find all the DOM element which acts as a container for a set of input elements with the same name as element
• getLinkedElement() - find the element in the DOM linked to source and return it
