 * Generates a form input element complete with label and wrapper div
 * HTML 5 ready!
 *
 * ### Options
 *
 * See each field type method for more information. Any options that are part of
 * $attributes or $options for the different **type** methods can be included in `$options` for input().
 *
 * - `type` - Force the type of widget you want. e.g. `type => 'select'`
 * - `label` - Either a string label, or an array of options for the label. See FormHelper::label()
 * - `div` - Either `false` to disable the div, or an array of options for the div.
 *    See HtmlHelper::div() for more options.
 * - `options` - for widgets that take options e.g. radio, select
 * - `error` - control the error message that is produced
 * - `empty` - String or boolean to enable empty select box options.
 * - `before` - Content to place before the label + input.
 * - `after` - Content to place after the label + input.
 * - `between` - Content to place between the label + input.
 * - `format` - format template for element order. Any element that is not in the array, will not be in the output.
 *    - Default input format order: array('before', 'label', 'between', 'input', 'after', 'error')
 *    - Default checkbox format order: array('before', 'input', 'between', 'label', 'after', 'error')
 *    - Hidden input will not be formatted
 *    - Radio buttons cannot have the order of input and label elements controlled with these settings.
 *
 * @param string $fieldName This should be "Modelname.fieldname"
 * @param array $options Each type of input takes different options.
 * @return string Completed form widget.
 * @access public
 * @link http://book.cakephp.org/view/1390/Automagic-Form-Elements
