on board to its island type.
Checks if guess hit any island on board and returns a response tuple.
Returns a map assigning the list of hits "cells" of each island
on board to its island type.
Returns the board's total number of hits.
Returns a map assigning to :squares the list of square numbers
from the board's misses.
Returns the board's total number of misses.
Returns an empty board struct.
Positions island on board and returns an updated board or
{:error, reason} if island overlaps another board's island.
