 * Examples:
 *
 * The text and for attribute are generated off of the fieldname
 *
 * ```
 * echo $this->Form->label('Post.published');
 * <label for="PostPublished">Published</label>

 * ```
 * echo $this->Form->label('Post.published', 'Publish');

 * ```

 * Generates a form input element complete with label and wrapper div

 *
 * 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().i
 * Additionally, any unknown keys that are not in the list below, or part of the selected type's options
 * will be treated as a regular html attribute for the generated 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. Set to `false` to disable any kind of error reporting (field
 *    error and error messages).
 * - `errorMessage` - Boolean to control rendering error messages (field error will still occur).
 * - `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.

 * Creates a set of radio widgets. Will create a legend and fieldset
 * by default. Use $options to control this
 *
 * You can also customize each radio input element using an array of arrays:
 *
 * ```
 * $options = array(
 *  array('name' => 'United states', 'value' => 'US', 'title' => 'My title'),
 *  array('name' => 'Germany', 'value' => 'DE', 'class' => 'de-de', 'title' => 'Another title'),
 * );
 * ```
 *
 * ### Attributes:
 *
 * - `separator` - define the string in between the radio buttons
 * - `between` - the string between legend and input set or array of strings to insert
 *    strings between each input block
 * - `legend` - control whether or not the widget set has a fieldset & legend
 * - `value` - indicate a value that is should be checked
 * - `label` - boolean to indicate whether or not labels for widgets show be displayed
 * - `hiddenField` - boolean to indicate if you want the results of radio() to include
 *    a hidden input with a value of ''. This is useful for creating radio sets that non-continuous
 * - `disabled` - Set to `true` or `disabled` to disable all the radio buttons.
 * - `empty` - Set to `true` to create an input with the value '' as the first option. When `true`
 *   the radio label will be 'empty'. Set this option to a string to control the label value.
 *
 * @param string $fieldName Name of a field, like this "Modelname.fieldname"
 * @param array $options Radio button options array.
 * @param array $attributes Array of HTML attributes, and special attributes above.
 * @return string Completed radio widget set.

/**
 * Returns a formatted SELECT element.
 *
 * ### Attributes:
 *
 * - `showParents` - If included in the array and set to true, an additional option element
 *   will be added for the parent of each option group. You can set an option with the same name
 *   and it's key will be used for the value of the option.
 * - `multiple` - show a multiple select box. If set to 'checkbox' multiple checkboxes will be
 *   created instead.
 * - `empty` - If true, the empty select option is shown. If a string,
 *   that string is displayed as the empty element.
 * - `escape` - If true contents of options will be HTML entity encoded. Defaults to true.
 * - `value` The selected value of the input.
 * - `class` - When using multiple = checkbox the class name to apply to the divs. Defaults to 'checkbox'.
 * - `disabled` - Control the disabled attribute. When creating a select box, set to true to disable the
 *   select box. When creating checkboxes, `true` will disable all checkboxes. You can also set disabled
 *   to a list of values you want to disable when creating checkboxes.
 *
 * ### Using options
 *
 * A simple array will create normal options:
 *
 * ```
 * $options = array(1 => 'one', 2 => 'two);
 * $this->Form->select('Model.field', $options));
 * ```
 *
 * While a nested options array will create optgroups with options inside them.
 * ```
 * $options = array(
 *  1 => 'bill',
 *  'fred' => array(
 *     2 => 'fred',
 *     3 => 'fred jr.'
 *  )
 * );
 * $this->Form->select('Model.field', $options);
 * ```
 *
 * In the above `2 => 'fred'` will not generate an option element. You should enable the `showParents`
 * attribute to show the fred option.
 *
 * If you have multiple options that need to have the same value attribute, you can
 * use an array of arrays to express this:
 *
 * ```
 * $options = array(
 *  array('name' => 'United states', 'value' => 'USA'),
 *  array('name' => 'USA', 'value' => 'USA'),
 * );
 * ```
 *
 * @param string $fieldName Name attribute of the SELECT
 * @param array $options Array of the OPTION elements (as 'value'=>'Text' pairs) to be used in the
 *      SELECT element
 * @param array $attributes The HTML attributes of the select element.
 * @return string Formatted SELECT element
 * @link http://book.cakephp.org/2.0/en/core-libraries/helpers/form.html#options-for-select-checkbox-and-radio-inputs
