 * @param {DiagonalMovement} opt.diagonalMovement Allowed diagonal movement.
 * @param {function} opt.heuristic Heuristic function to estimate the distance
 *     (defaults to manhattan).
 * @param {number} opt.weight Weight to apply to the heuristic to allow for
 *     suboptimal paths, in order to speed up the search.
 * @param {number} opt.avoidStarcasing Add penalties to discourage turning and
 * causing a 'staircase' effect (defaults to false).
 * @param {number} opt.turnPenalty Penalty to add to turning. Higher numbers
 * discourage turning more (defaults to 1).
