/* ЗАДАЧА 1
 * 
 * Дано:
 * 	- Текст из *.csv файла
 * Необходимо:
 * 	1. Распарсить текст, подготовить данные к работе (элемент = тип Объект)
 * 	2. Отсортировать данные по дате затем КБК и вывести в таблице, таким образом, что если существует несколько записей на одну дату с одним КБК, то в поле %% считать среднее, а в скобках вывести кол-во елементов.
 * 
 *  Пример Табл.:
 *  | ДАТА       | КБК      | Адрес             | %%      |
 *  | 11.01.2013 | 1-01-001 | Спб, Восстания, 1 | 84% (2) |
