# create driver test code to retrieve a value at a coordinate here:
puts boggle_board.board[3][2] == "k"

# for get diagonal
# I would input the first coordinate of the start of the diag
# and the last coordinate of the end of the diag
# create an array, push in first letter using first coord
# increment each first and last of the first coordinate by 1
# until it reaches the same value as the last coordinate
# return array
