Change logs:
1. When porgram just built RESUME button should be unactive. After NEW_GAME is pressed RESUME button will appeared.

3. Found exception in drawing method. It throws when programm is builds. Created try-catch box.
4. I decided to change architecture of snake object - right now is only one class, which contains collection of  objects like head and cells. These object are inside Snake.class.
5. Initializing of a snake is ready. The method initSnake creates head and three cells, located horizontaly
6. Program draw snake when program state is running. When it is on Pause, program does not paint snake.
