initial commit for the array chess board example
created starting point for chess board
replicated the example on MDN for moving the pawn two spaces forward.
Alrighty, that wasn't too bad. Lucky for me, I know how to play chess and know how the pieces move. Not that it's required for this assignment, but it probably helps a little. Anyways, this exercise focused on visuazling the index locations of arrays within an array. Good stuff.
