Постановка задачи:
Реализация работы со справочником предметной области “Магазин”( с ключами Артикул, Наименование товара, ИНН поставщика,  Дата) с использованием структур данных АВЛ-дерево (по нему распределяем по ключу Наименование товара), состоящее из хеш-таблиц (по ним распределяем по ключу Дата).
Общие требования:
Оконный интерфейс (среда разработки WinForms)
Нельзя использовать универсальные классы-коллекции в System.Collections для реализации заданных структур данных
В интерфейсе отображать справочник в табличном виде и окно отладки для вывода структур данных
Какой должен быть функционал: 
Возможность задания в интерфейсе первоначального размера ХТ
Работа со справочником:
- загрузка из текстового файла / сохранение в текстовый файл
- добавление
- удаление
- поиск
- просмотр
Окно отладки (печать структур данных)
Форма использует файлы Kursovaya.cpp, MyForm.h и MyForm.cpp.
