//_keys - массив ключей (values) для checkbox-ов. Имена checkbox-ов - unique_name[keys[1]], unique_name[keys[2]] и т.д.
//_values - массив значений (подписей) для checkbox-ов. Соотв. массиву keys;
//_unique_name - уникальное имя для элемента;
//_text_info - список падежей подписей, например: new Array("элемент", "элемента", "элеиентов"); (Нарпимер, "выбрано 5 элементов")
//_unique_name - массив выбранных значений (keys);
//_formname - имя формы
//_any - подпись для элемента. озн. выбрать все. Если элемент не нужен - пустая строка "";
