  4.    Assumes that 'hand' has all the letters in word.
  5.    In other words, this assumes that however many times
  6.    a letter appears in 'word', 'hand' has at least as
  7.    many of that letter in it.
  8.  
  9.    Updates the hand: uses up the letters in the given word
  10.    and returns the new hand, without those letters in it.
  11.  
  12.    Has no side effects: does not modify hand.
