Parallel version has now been split from spatial version.
0.8.3
Removed the crawl procedure from the graph consolidation method and replaced with a `by_neighbours` strategy. This approach better preserves topology.
A subsequent improvement would be to split parallel geometries where nodes are out of lock-step. This may remove the need for decomposition steps prior to final consolidation.
0.8.2
Generalising mock_osm_graph method to work with user-supplied OSM json
0.8.1
Resolved an issue where nodes in WGS graphs spanning UTM zones could be converted to different zones.
