add_vertices_lines

Add vertices (feature collection of points) to their nearest lines
(feature collection of linestrings), may fail if the line geometries are self intersecting.

internal

Perform spatial analysis on network.
Implement several methods for spatial analysis on network: Network Kernel Density estimation,
building of spatial matrices based on network distance ('listw' objects from 'spdep' package), K functions estimation
for point pattern analysis on network, k nearest neighbours on network, reachable area calculation, and graph generation
