 ### Graph
 
 - changed navigation CSS. Icons are now always correctly positioned.
 - added stabilizationIterations option to graph.
+- added loadXYinDataset() method to save the XY positions of nodes in the dataset.
+- seperated allowedToMove into allowedToMoveX and allowedToMoveY. This is required for initializing nodes from hierarchical layouts after loadXYinDataset().
