Краснояров - Лабораторная работа #1

@ljaljushkin, @bysheva please review
Try to use `setUp`(@Before annotation) method for repeated initialization. We can set up tools (copy-paste detector) to say you, that `List<Double> values = Arrays.asList(1.0, 2.0);` (and some other initialization) line in many tests is copy-paste, but we hope, you can fix it.
