/*
* This logic code makes use of the utility metric to make its decisions in as close to an approximation to human behavior has possible,
* basing its choices on Maslow's Heirarchy of Needs. It is called on each update, and performs the following procedure:
*
* 1. Calls the utility's Decay function, emulating regular use of resources such as food and energy.
*
* 2. Examines remaining utility and determines what is the highest priority based on increasing preference to lower levels of the heirarchy.
* For example, if the agent is low on hunger, they will attempt to find food. If both hunger and energy (1st level) are satisfied
* and there is no immediate danger(2nd level), the agent will reach out into social activities(3rd level)
*
* 3. If there are no immedaite needs, the agent will attempt to predict a future possible need and if action is required, such as
* working a farmland for food now so that there is food available later, even if the agent is not immedaitely hungry.
*
* 4. Once the end result is determined, the agent will search through its knowledgebase for a world object that will satisfy its
* decision. World objects include houses, farmland, stores, and even people. Agents have a limited 'vision', and must discover new
* objects before they are added to its knowledgebase. The choice of object to use will depend on its available and relevant utility,
* and its distance from the agent (particularly for time-critical utility like food).
*
* 5. After an object to use is selected, the coordinates for that object are set as the new destination and the agent moves toward
* their destination.
