How to fix Complexity

<?php
/**
 * Displays a set of checkboxes as a logical group.
 *
 * ASSUMPTION -> IF you pass your source as an array, you pass values as an array too. Likewise objects are handled
 * the same.
 *
 * Example:
 * <code>
 * new CheckboxSetField(
 *  $name = "topics",
 *  $title = "I am interested in the following topics",
 *  $source = array(
 *      "1" => "Technology",
 *      "2" => "Gardening",
 *      "3" => "Cooking",
 *      "4" => "Sports"
 *  ),
 *  $value = "1"
 * );
 * </code>
 *
 * <b>Saving</b>
 * The checkbox set field will save its data in one of ways:
 * - If the field name matches a many-many join on the object being edited, that many-many join will be updated to
 *   link to the objects selected on the checkboxes.  In this case, the keys of your value map should be the IDs of
 *   the database records.
 * - If the field name matches a database field, a comma-separated list of values will be saved to that field.  The
 *   keys can be text or numbers.
 *
 * @todo Document the different source data that can be used
 * with this form field - e.g ComponentSet, ArrayList,
 * array. Is it also appropriate to accept so many different
 * types of data when just using an array would be appropriate?
 *
 * @package forms
 * @subpackage fields-basic
