DialogueNode class

An individual narrative unit inside a DialogueGraph.

Each node has a unique title, optional tags and header metadata, and a list of statements that are executed in order.

In Yarn Spinner a node looks like:

title: Innkeeper_Hub
tags: hub npc
---
Innkeeper: Good day, traveler.
-> Ask about quest.
    <<jump Innkeeper_Quest>>
-> Farewell.
