INSTRUCTIONS:

On each turn, the display should show who the current player is.

The board should get filled from bottom to top just like in real life.

After a player drops their marker into the column of their choice, the program should check if he/she is a winner.

If the current player is a winner update the display label to reflect the status and ask if they want to play again.

Otherwise, the alternate player should take a turn.

If the board is full, check for a winner or a tie. Update the display label to reflect the status and ask if they want to play again.

EXTRA CREDIT:

Use image icons on the labels to display a marker when a slot is filled by a player taking a turn (5pts extra)

Create a ConnectX game so that the user can play connect4, or connect5, .. or connectX where they choose how many they would like to be in a row to be considered a win (15pts extra) - must check all diagonals
