himach v0.2.3
Since the last release:
- Fixed crash when routing over very short hops (say for re-positioning flights).
- (development) Bug fixes: map leakage solved, summarise_routes now works with 3-letter airport codes as well as 4 (though default is still ICAO codes, not IATA codes for airports).
- and then made it work on solaris running old GDAL: switch to storing crs_Atlantic etc as strings.
