value2issue: Low: Water
Medium: Food
High: Firewood
value2reason: Low: I brought a filtration kit so I can make my own drinking water from the nearby creek.
Medium: Some of the food I brought has spoiled so I need extra food.
High: My sleeping bag is thin and not very warm so I need extra firewood to keep myself warm at night.

Participant mturk_agent_2's preferences:
value2issue: Low: Water
Medium: Food
High: Firewood
value2reason: Low: I would require water over food, as it is a more essential than food. 
Medium: I am a good cook, and therefore allowing me to have the food, I would ensure that meals are at the very minimum decent. 
High: I have a medical condition that requires me to not get cold. The firewood is a life or death essential for me. 

Negotiation dialogue:
mturk_agent_1: Hello! Which item do you need the most?

mturk_agent_2: I would love to have the Firewood the most. 

mturk_agent_1: Unfortunately I need firewood the most too. How about I take 2 firewood, 2 food, and 1 water?

mturk_agent_2: I feel that I am not getting a fair deal. 

mturk_agent_1: Then what do you think is fair?

mturk_agent_2: I think that I should get 2 firewood, 1 food and 2 water

mturk_agent_1: I will let you have 2 firewood if you let me have 3 food, 2 water, and 1 firewood.

mturk_agent_2: That would leave me with no food. I counter with 2 firewood 1 food 1 water. 

mturk_agent_1: Well, with the extra firewood you are getting you will be able to cook your own food.

mturk_agent_2: So to recap the deal is that I will get 2 firewood, 0 food, and 1 water
