 *
 * methodology:
 * in order to store the score in a way that allows for it to be
 * converted between different base systems, we store the score 
 * of the game in a vector where the ith spot holds the number of 
 * times a block of power i has been created by the merging of two
 * blocks.
 *
 * to calculate the score:
 * sum ( (base^i) * vector[i]) for all i in vector
