+3.11 - 25 Sept 2018
+More LIDAR edge cases, tidying of many meridian hacks(!) and regression tested with different LIDAR resolutions and configurations eg. 1x2, 2x1..
+Meridian issue fixed for 30m but deliberately broken for 2m due to previous crap hacks causing a headache. Can be fixed in DEM by re-processing LIDAR tiles to NOT span the meridian.
