# IN THIS SAMPLEVERSION: Choose a random word from the wordlist.  Make a list of
#  neighbors, nbrs, that consist of the words in wordlist that are 1 letter 
#  different from the previous word in this list. This version iterates through this process 
#  5 times, each iteration finding a word 1 letter different from the current word.
