Markov Chain Algorithm

"... an implementation of the Markov chain algorithm, described by Kernighan & Pike in their book The Practice of Programming (Addison-Wesley, 1999). The program generates pseudo-random text based on what words can follow a sequence of n previous words in a base text. For this implementation, we will assume that n is two."
