# implement tests for each of the methods here:
boggle = BoggleBoard.new(dice_grid)
p boggle.create_word([1,2],[1,1],[2,1],[3,2]) == "dock"
p boggle.get_row(0) == ["b", "r", "a", "e"]
p boggle.get_row(3) == ["t", "a", "k", "e"]
p boggle.get_col(0) == ["b", "i", "e", "t"]
p boggle.get_col(2) == ["a", "d", "l", "k"]

# create driver test code to retrieve a value at a coordinate here:

p boggle.get_letter(3, 2) == "k"
p boggle.get_letter(0, 0) == "b"

Creating a BoggleBoard class obviously involves more code, but it is somehow easier to manage conceptually, and I imagine it's
much easier to actually manage the code as well.  I'm still unsure as to when it's best to create a separate method for a task
versus including it within another method, or writing the method call in such a way as to get the behavior I want, but I imagine
that understanding will come with time.  

I wrote the "show-all" method(s) so that each row and column includes a "row #:" or "column #" string so that it is easier to read
the output.
