 * This class handles the logic specific to a "free" game.

 * The algorithm is simple: players play at their turn, and they can either
 * play a word or change letters (changing letters implies passing its turn).
 *
 * When a player has no more letters (end of the game), the points of the
 * letters left in the racks of his opponents are added to his score, and
 * removed from the score of the latters.
