Represents one Conversation that a Player would hold with an NPC.

Each Conversation has options that a Player can use the Say Command to say. Since this class implements InvokableItem, each conversation can perform one action at time of each conversation starting.

A general conversation flow goes something like this:

-> player talks to npc

-> npc conversation starts
    -> conversation onInvoke called
    -> conversation message and options displayed

-> player says an option

-> get conversation child from option
    -> conversation onInvoke called
    -> conversation message and options displayed

-> repeat until no more options or player leaves conversation
