- code improvement
- dump location api change
>>> import Gryd
>>> dublin = Gryd.Geodesic(-6.272877, 53.344606, 105.)
>>> # mapbox static map api url
>>> url = "https://api.mapbox.com/styles/v1/mapbox/outdoors-v11/static/"\
... "pin-s+f74e4e(%(lon)f,%(lat)f)/%(lon)f,%(lat)f,%(zoom)d,0/"\

geohash
module improvement- implementation based on python integers
- better encryption interface
1.2.0
- added

module
1.1.1
Geodesic
class can now dump thumbanil location from google staticmap API- bugfix in unit usage for classic projection (other than grid)
1.1.0
- projection core changes (simpler & faster)
- added
miller
andeqc
projection - 64 bit support for Windows
- encrypt/decrypt geodesic coordinates
>>> point = Gryd.Geodesic(-6.23, 53.63)
>>> point.encrypt("your encryption key")
'mwszncbe9g2tu29'
>>> Gryd.decrypt('mwszncbe9g2tu29', key="hacking...") # gives coordinates but not the good ones
Geodesic point lon=+025°22'0.011'' lat=-086°36'35.290'' alt=0.000
>>> Gryd.decrypt('mwszncbe9g2tu29', key="your encryption key")
Geodesic point lon=-006°13'48.000'' lat=+053°37'48.000'' alt=0.000
>>> point
Geodesic point lon=-006°13'48.000'' lat=+053°37'48.000'' alt=0.000
