/**
 * A small amount of common code that can be usefully applied to adder forms.
 *
 * An adder is assumed to be an object that has:
 *
 * .fields  A object mapping field names to either validation functions used
 *          for text fields, or the word 'checkbox'
 * 
 * .createForm  A function () that returns a newNode('form') to be added to the
 *              document (by appending to insertNode)
 * 
 * .onsubmit  A function (values, register (wikitext, callback)) that accepts 
 *            the validated set of values and processes them, the register
 *            function accepts wikitext and a continuation function to be 
 *            called with the result of rendering it.
 *
 * Before onsubmit or any validation functions are called, but after running
 * createForm, a new property .elements will be added to the adder which is a
 * dictionary mapping field names to HTML input elements.
 *
 * @param {editor}  The current editor.
 * @param {adder}  The relevant adder.
 * @param {insertNode}  Where to insert this in the document.
