Made FiveGuess1.java algorithm, but it doesn't work.
Renamed Pattern to Pegs, because Pattern is an existing Java class. Oops. Also created a Reply class that is the output of Evaluate, and holds the # matches and misses.
Merge branch 'dev'.
Made a new algorithm that narrows down the search space exponentially on each successive turn. Maybe this is how the five-guess algorithm is supposed to work?  I'll explain it in the writeup.
