•	Made String welcomeMessage private in Sudoku.java class
•	Moved Strings correctMessage and incorrectMessage to top of Sudoku.java class as good coding practice to put instance variable at the top.  Also changed them to private.
•	Changed newGame function under Grid.java class to be static since it is a public function
•	Removed blockCheck function from Sudoku.java as it should be a function in the grid or gameboard class.  It wasn’t even being used and we had already created a new function under grid to do what the blockCheck function was doing so we must have just forgotten to delete it.  A good example of bad cohesion though.
