Rock, Paper, Scissors, Lizard, Spock

/*
    This program emulates the version of rock, paper, scissors popularized 
    by the tv series "Big Bang Theory". This variety utilizes the typical 
    rock, paper and scissors paradigm while adding lizard and spock to the
    equation. (scissors > paper > rock > lizard > spock > scissors > lizard >
    paper > spock > rock > scissors)
