In a tile matching game, tiles are arranged on a grid with rows and columns. Two tiles are turned over at a time, and if they match, the player earns a point. If they are adjacent, the player earns an additional point. Implement such a game, using classes Tile, Location (encapsulating a row and column), Grid, and MatchingGame. You can implement the game using pictures, as in Section 8.5, or tiles with words. When designing your classes, pay attention to cohesion and coupling.
