		# range of 1 - 3, then iterate through the boards at the current allBoards element
		# then decide what string to concatenate to the row string.
		# the allBoards list contains three elements, each of which representing the three
		# horizontal board groups, or three lists of three board values, the values being
		# either ' ', 'X' or 'O'
		# the first loop iterates through these horizontal rows (three times)
		# the next loop iterates through a range of 1 - 3, this is needed to use the 'i' value
		# the next loop iterates through the trio of boards at the current allBoards element
		# these boards represent the first horizontal row of the outer board
		# using the 'i' value from the middle loop, the rows of the inner boards are selected
		# and concatenated to the row string
		# the combination of loops works its way through all the inner boards and prints out
		# each row and value contained in each square
		# if the board is the current board, the board is highlighted white to indicate the active board
		# if player X has won that particular board, it is highlighted red
		# if player Y has won that particular board, it is highlighted green
		# else the board is not highlighted
