Overview
| Comment: | Yay! Working prototype. Will sum up the distances of headwinds... ...for a polyline route. I'd made silly mistakes like forgetting which order the list of tuples were in. I.e {Distances, Wind} or {Wind, Distances}. It doesn't really matter which order I use, but I should back sure it is consistent and matches the variable naming. Now need to extend this to sum up all wind directions and check for other bugs (such as sum of distances making sense, headwinds are actually headwinds and not tailwinds, etc). |

| 11:02 | Extend functionality to sum up all wind directions by mapping. Need to tidy up formatting and make it consistent and sort out the naming of variables - it's such a mess. check-in: 6912ce6208 user: base@atomicules.co.uk tags: trunk, origin/master | |

| 17:42 | Merge branch 'master' into osrm Noticed the nth_wrap problem whilst developing this osrm branch as building the list of winds would be incomplete. check-in: 915a1fb3d0 user: base@atomicules.co.uk tags: trunk, origin/master | |
