// This is some sample code for the comparator class.
// You will need to change the return value of the 
// operator() function to reflect the heuristic specified
// in the handout.  Feel free to add private methods to
// this class if it will help you perform the calculation.
// Feel free not to use this class at all.  Feel free to
// make any changes you want to it.  It's just included
// to give you an idea of what you might want to do.
// You might want to use these functions:
//   SquareMaze::SquareMazeNode::getMazeWidth()
//   SquareMaze::SquareMazeNode::getMazeHeight()
//   SquareMaze::SquareMazeNode::getExitX()
//   SquareMaze::SquareMazeNode::getExitY()
// You'll also have to have some way of figuring out how
// many steps it took to get to the current node.
