// 1. CompositeKeyCollection<TKey1, Tkey2, TData> - обычная обобщенная реализация класса коллекции (не потокобезопасная)
// 2. ThreadSafeCompositeKeyCollection<Tkey1, Tkey2, TData> - потокобезопасная реализация класса CompositeKeyCollection<TKey1, TKey2, TData>
// 3. TransactionalCompositeKeyCollection<TKey1, TKey2, TData> - класс коллекции с комопозитными ключами и поддержкой транзакционности на операции вставки и удаления записей в коллекцию (PS.: пока еще не потокобезопасная)
// Примеры использования коллекций:
// 1. CompositeKeyCollection<TKey1, Tkey2, TData>
