CodeGym mini project - level 30 - 2048 game

This project implements 2048 game. Features:

1. Fully working game, merging tiles and adding random new ones to the board
2. Undo move option
3. Random move option
4. Auto move option (based on simple algorithm to find best move)

Task completed. My takeaways:
-> Practice with data structures (2d arrays, Stack)
-> More practice with MVC pattern
-> Practical use of Functional interface and method referencing
-> Getting familiar with reading KeyEvents and connecting appropriate model methods to these
-> A lot of practice with commenting code - there were several complex methods that would be difficult to understand for someone not familiar with the code
