// An example of some of the FastStorage methods that were overloaded are:

inline void AddNodeToOpenList(AStarNode* inNode)
{ // call base class version.
	AStarStorage::AddNodeToOpenList(inNode);
	// Add it to our own node sliding window array.
	this->AddNodeToNodeTable(inNode->mX, inNode->mY, inNode);
}

inline AStarNode* FindNodeInClosedList(long inX, long inY)
{ // the flags array will tell us if we should return it
	if(this->GetIsClosed(this->GetFlagForTile(inX,inY))
		return this->GetNodeFromNodeTable(inX, inY);
