The instructions for the bonus '#get_diagonal' state, "method should return an array of values, but it will need 2 coordinates
entered to define the diagonal.

So just like the '#create_word' method, I assume they want to arguments that are coordinates, i.e. get_diagonal([1,1], [2,2])

My question is, what exactly are we supposed to return? The exercise says an array of values, but do they just want the two
values passed to '#get_diagonal' if they are diagonal? For example, using the dice grid above, get_diagonal([1,1], [2,2])
would return ["o","l"] or I suppose, ["l","o"], but should it also return the rest of the values that are directly diagonal
from these letters, ["b", "e"] ?
