Game Global Variables:

The values of the Game Object properties are determined by the user-selected difficulty.

The Game Object contains the following properties:

difficulty: String, The difficulty of the puzzle, (easy, medium, hard)
numToWin: Integer, the number of blank spaces of the puzzle. This is decremented each time a user places a correct number
puzzleId: Two dimensional array of integers. Contains the Answer-Key of how the completed puzzle should look
puzzleToLoad: Two dimensional array, containing the initial puzzle appearance, with 0's for the blank spaces that are loaded

selectedNumber: Integer, represents the selected number of a row of buttons 1-9. While a certain number is selected, that is the number that will be placed on the grid when the individual cells are selected.
numHints: Integer, the number of currently requested hints by the user
numErrors: Integer, the number of accumulated errors the user has commited

The following functions belong to the Model of the Sudoku Game

pickGame():
This function will take the game difficulty value picked by the user, and create a game object with the associated values for the difficulty (easy, medium, or hard).
giveHint():
This function will find a randomly generated blank spot in the sudoku grid, place a value in it, and increment the numHints variable.
checkValidNumber():
This function will take the number just inserted into the cell of the table, and check it against the two dimensional array of the correct numbers for that particular puzzle.
correctNumber():
This function is called if the inserted number is in the correct place. It decrements the number of cells left over until the game has been won.
wrongNumber():
This function is called if the inserted number is in the incorrect place. It will discard the number, and increase the number of errors in the numCurErrors variable.
checkGameWin():
This function is called from the correctNumber() function, to update and check the numToWin variable to see if the game is now complete.
checkGameLose():
This function is called from the wrongNumber() function, to check the numErrors variable against the max NUMERRORS constant to see if the game is over.
gameWin():
This function is called from the checkGameWin function if the game has been won. It takes the game statistics and resets the game variables, then calls a render function to render the game win overlay.
