• Add methods to create a sub-OSMGraph from an OSMGraph (#71) (@bjmommers)

LightOSM v0.2.0

Diff since v0.1.19

Changes:

• Improve Djkstra and A* performance using min heap instead of priority queue
• Use correct exit conditions for Dijkstra and A*
• Introduce breaking change to shortest_path interface and traversal functions astar and dijkstra, mainly to minimise allocations
• Add cost_adjustment function as input to path finding, generalises restriction costs between u and v
• Improve path_from_parents by tracking path length, allows preallocation of final array
• Add graph utilities like index_to_node_id, more to come in the future
• nearest_node updated so now only returns a single node for each point given. If a single point is given (whether a GeoLocation, vector of lat/lon, Node or node ID) then a tuple of (id, dist) is returned. If a vector of points is given, then a tuple of ([ids...], [dists...]) is returned.
• Added nearest_nodes allows for the nearest n nodes. If a single point is given, returns a tuple of ([ids...], [dists...]). If a vector of points is given, returns a tuple of ([[ids...]...], [[dists...]...]).
• Concretely type kdtree field of OSMGraph - improves performance
• Quite a bit of refactoring including removing function return typing - we can let Julia work this out.
• Rename highways to ways

Closed issues:

• Refactor highways to ways in graphs (#18)
• Change nearest_node API (#45)
• shortest_path throws an error when no path is found (#61)
• Try FastPriorityQueues.jl (#68)
