* 'master' of https://github.com/ludovicl/IA54_taquin:
  GUI v1.0 - Abandoned the idea of reusing the GUI code from the practical, too f*cked up - Restarted the GUI from scratch based on web tutorials: http://www.ntu.edu.sg/home/ehchua/programming/java/JavaGame_TicTacToe.html See 4.3 Sudoku Now we have something that actually works! - Have implemented a refresh() method that should later be called after each iteration to update the puzzle
  GUI v0.3: - More work done trying to fix the NullPointerException line 37, still no success, has to do with an initialization problem - added refresh() method which will be later used to repaint the puzzle after each iteration
