 Помощь в обработке клиентских заявок путем поиска продукции РЕХАУ по запросу, выраженному в свободной форме, и в работе с прайс-листом BS РЕХАУ

 ## Реализованные функции
+- Поиск артикула с помощью `=RHSOLUTIONS()`
 - Экспорт массива ячеек вида "Артикул - Количество" в прайс-лист
 - Актуализация прайс-листа до последней версии
 - Объединение нескольких прайс-листов в один файл
- Поиск пар артикул-количество в любой сторонней таблице и экспорт в таблицу заказов
- Подбор монтажных гильз для фитингов RAUTITAN
- Подбор ремонтных муфт по количеству трубы
- Экспорт таблицы заказов в девятиграфку по ГОСТ
+    - Сложением всех позиций по артикулам
+    - С разнесением данных по колонкам в конечном файле

 *Для работы функций "Экспорт", "Актуализация" и "Объединение" требуется указать путь к файлу пустого прайс-листа РЕХАУ*

-## Реализованные формулы для работы с артикулами
- ```=РЕХАУ()``` - поиск артикула РЕХАУ по произвольному запросу в сервисе [RhSolutions-Api](https://gitea.cebotari.ru/chebser/RhSolutions-Api) 
- ```=РЕХАУАРТИКУЛ()``` - экстракция артикула РЕХАУ из любой строки по регулярному выражению
- ```=РЕХАУИМЯ()``` - поиск названия артикула по номеру
- ```=РЕХАУЦЕНА()``` - поиск цены в евро по номеру артикула
- ```=РЕХАУЦЕНАРУБ()``` - поиск цены в рублях по номеру артикула и курсу ЦБ на любую дату
- ```=КУРСЕВРО()``` - курс евро ЦБ на дату
-
 ## Установка
 1. Скопировать файл плагина в папку 
 ```
