/**
 * Primary value passed to this field must be the 'given' name.
 * it cannot be NULL, but may be an empty string.
 *
 * Arguments are used to specify all the other values:
 * 'title' => array('source_field' => 'title'),
 * 'middle' => array('source_field' => 'middle'),
 * 'family' => array('source_field' => 'family'),
 * 'generational' => array('source_field' => 'generational'),
 * 'credentials' => array('source_field' => 'credentials'),
 *
 * Add the source field mappings to the argument array then add null mappings to
 * avoid having fields flagged as as unmapped:
 * @code
 *   $arguments = array(
 *    'title' => array('source_field' => 'profile_title'),
 *    'middle' => array('source_field' => 'profile_middle_name'),
 *    'family' => array('source_field' => 'profile_last_name'),
 *   );
 *   // The given name should be passed in as the primary value.
 *   $this->addFieldMapping('field_name', 'profile_first_name')
 *        ->arguments($arguments);
 *   // Since the excerpt is mapped via an argument, add a null mapping so it's
 *   // not flagged as unmapped.
 *   $this->addFieldMapping(NULL, 'profile_title');
 *   $this->addFieldMapping(NULL, 'profile_middle_name');
 *   $this->addFieldMapping(NULL, 'profile_last_name');
 * @endcode
