worldstate: states at this node
action: action that led (regressively) to this node (and that should be run when executing this path forwards)
possible_prev_nodes: nodes with actions that the planner found possible to help reach this node
(empty until planner ran, used for visualization/debugging)
parent_nodes_path_list: nodes that led (from the goal) to this node
parent_actions_path_list: actions that led (from the goal) to this node
note that the parent path lists begin with the goal node and end with this node's parent
if this node is the goal node:
- the action is None
- the path lists are empty
- also, cost() and heuristic_distance are zero
