Newstyle wed

### Utility (j)

 - Network Edge Segmentation
 - Assignment of Counts/Rates to segments, nodes, edges
 - ~~Network Edge Length~~
 - ~~Snapping off-network objects to network~~
 - ~~Single shortest path (Dijkstra's) (One node and all other nodes)~~
 - ~~Shortest Path (Path between two nodes)~~
 - ~~Network Connectivity~~
 - Extended shortest path
 - Network Voronoi Diagrams ?
 - Simulated points on a network
 - ~~Threshold distance~~
 - Network Center
 - Intersection with buffering (s)
 - Node insertion / deletion

 - ~~Winged Edge Data Structure~~
 - ~~Extraction of WED from a planar polyine shapefile~~
 - Spatial Weights for Networks
     - Link Contiguity
         - ~~First Order~~
     - Distance Based
         - KNN
         - Threshold   
 - Handle direction
