Integrate a Routing application, e.g.
 * [http://project-osrm.org OSRM] - new, blindingly fast C++ implementation
 * [http://wiki.openstreetmap.org/index.php/YOURS OpenStreetMap's Gosmore]
 * [http://pgrouting.org pgRouting]


Can this use the same database as used to serve Tiles?

Should we have Roads be a resource inside Sahana?

== Use Cases ==
* Calculate walking/driving distances (Include Topology where-available)
* This can then later be extended to working out which routes different trucks should take to deliver their Shipments
