All Implemented Interfaces:
TaskRunner
public class AITaskComponent extends Component implements TaskRunner
Task-based AI component. Given a list of tasks with priorities, the AI component will run the highest priority task each frame. Tasks can be made up of smaller sub-tasks. A negative priority indicates that the task should not be run.

This is a simple implementation of Goal-Oriented Action Planning (GOAP), a common AI decision algorithm in games that's more powerful than Finite State Machines (FSMs) (State pattern).
