| Comment: | Commit in haste: Repent at leisure. Fix reverse journey
Had not actually tried out my changes, or, it seems, used my brain at all - Can't simply just add Pi on, need to keep it within 2*Pi limit |

Bug fix - Forgetting than list indexes start at 1
Which means I also need to wrap around the list if I get 16 segments. This means I probably could have just simply added Pi (previous commit) | |

Handle the reverse route
I don't want to have to query OSRM for th ereverse route - it's In order to do this made sense to re-jig some of the functions a bit: - Need date and time at top level, not buried in get_weather since | |
