                        The way this checks the if someone won is:
                        First: it checks if the btnEmpty[x] is not equal to an empty string-    x being the array number 
                            inside the multi-dementional array winCombo[checks inside each of the 7 sets][the first number]
                        Secong: it checks if btnEmpty[x] is equal to btnEmpty[y]- x being winCombo[each set][the first number]
                            y being winCombo[each set the same as x][the second number] (So basically checks if the first and
                            second number in each set is equal to each other)
                        Third: it checks if btnEmtpy[y] is eual to btnEmpty[z]- y being the same y as last time and z being
                            winCombo[each set as y][the third number]
                        Conclusion:    So basically it checks if it is equal to the btnEmpty is equal to each set of numbers
