  Returns:
    the list of arcs which apply to every state

### makeDoNotUnderstoodArc

    public void makeDoNotUnderstoodArc()

  Makes a "do-not-understand" arc for every conversation state. Initial state is current-state. 1. If we are in the current-state state and get a not-understand performative, transition to the current-state state, and perform the do-not-understand action.

### makeQuitArc

    public void makeQuitArc()

  Makes a "quit" arc for every conversation state. Initial state is current-state. 1. If we are in the current-state state and get a quit performative, transition to the final state, and perform the do-finalization action.

### makeChat

    public Conversation makeChat()

  Makes a "chat" Conversation. Initial state is ready. 1. If we are in the ready state and get a term-query performative, transition to the ready state and perform the do-term-query action.

### makeTermQuery

    public Conversation makeTermQuery()

  Makes a "term-query" Conversation. Initial state is retrieve-fact.
  1. If we are in the retrieve-fact state and get a term-query performative, transition to the prompt-for-more state and perform the reply-with-first-fact action.
  2. If we are in the prompt-for-more state and get a more performative, transition to the prompt-for-more state and perform the reply-with-next-fact action.
  3. If we are in the prompt-for-more state and get a done performative, transition to the done state and perform no action.
