    Problema: The Tea Party
              http://codingkata.org/katas/unit/tea-party

    Your task is to welcome your guests properly: Some are female and some were knighted by the queen.
    So greet them correctly – or this will be your last hosting.
    For example:
    -Jane Austen is a women, so say Hello Ms. Austen
    -George Orwell is a man, so say Hello Mr. Orwell
    -Isaac Newton was knighted, so say Hello Sir Newton
