/**

 * Reusable functions such as those to show error messags and validating fields

 *
 * To set up a new form to be handled by ajax, create the following 3 functions,
 * see formGeneratePin_*() for an examples.
 *
 *  1. formFORMNAME_Init();
 *         Use this to set up the form, call .ajaxForm() and set up default text
 *         in fields, see
 *  2. formFORMNAME_Validate();
 *          Performs form validation and calls showInputErrorsBoxes() to show the
 *          error messages. Returns the value of showInputErrorsBoxes
 *  3. formFORMNAME_Response();
 *          Handles the ajax response by showing or hiding any relevant divs
