+-- NPC Chat code by Zorman2000
+-- Chat system consists of chatline and options objects that are re-used to create a conversation. 
+-- The objects are the following:
+-- 
+-- chatline = { text = "", options = {}, name = "", flag = "" }
+--  1. text: What the NPC says on this chat line
+--  2. options: What the player can answer to the chat line. Options are of another type of chat lines.
+--              If you want the player to have no options to answer, set to nil
+--  3. name: The name of the NPC that will use this line. Use this when you want a specific NPC
+--           to speak this line.
+--  4. flag: When the NPC speaks this line, this flag will be set into the entity's metadata.
+--
+-- options = { opt = "", answer = { chatline }
+--  1. opt: The text that the player can say to the NPC
+--  2. answer: A chatline object (as described above)
+-- 
+-- Example of conversation hierarchy
