Feel free to use the layer code from worldmap. I'd be happy to help you out if you have any questions about it. There's a new LayerCategory model, and the Layer model's category field was changed to be a foreign key to that. Users can also change the layer's category name within a map, which is saved in the MapLayer's 'group' field.
