Constructing a soldier blackboard

Previously, we stored any data from evaluators and actions on the userData structure. We can now move all this data to our blackboard. The following is the list of attribute values we'll be storing within the blackboard:

Blackboard attributes	Description
alive	Whether the agent is considered alive or dead
ammo	The current amount of ammunition the soldier's rifle has left
maxAmmo	The clip size of the soldier's rifle
maxHealth	The starting health of the agent
enemy	The best enemy agent that can be attacked
bestFleePosition	The best strategic position to avoid enemy agents

Constructing a blackboard requires you to set the initial attribute values we previously stored on the soldierUserData table directly. At this point, we can create KnowledgeSource instance implementations for enemy selection and flee position calculations. To allow access of the blackboard to all our agent systems, we can store the blackboard itself on soldierUserData...
