# Добавлен файл программы, проводящей анализ файла .gcode и на основе полученных данных вычисляющая материальные и временные затраты на 3д-печать.
# Программа вычисляет габариты задания, длину затрачиваемой нити филамента, длительность маршрута движения головки принтера и длительность печати.
# Эксперименты показывают, что на данный момент есть расхождение между реальным временем и вычисленным с помощью программы,0 в зависимости от файла, на 20-40% (недооценка вычисленной длительности в сравнении с реальной). Остальные результаты выглядят адекватными, но проверить их сложнее.
