-- Major refactoring splitting into more logical file/modular structure
-- Use autoload
-- Extract GeoUnits
-- Extract Dms with converter
-- GeoPoint can now have set :coords_mode which affects how Ruby Core objects such as String and Array are parsed into :lng and :lat. 
+Extracted GeoUnits and GeoPoint into separate gems: 
 
-TODO:
-- The GeoPoint class should be extracted into separate gem, then this geo_calc gem should only have the more generic geo functionality as modules to be included
-where needed in other gems!

-h2. Objetive
+h2. Objective
 
 The objective of this library is to act as a base for other geo libraries. 
 
-Please take a look at "geo vectors":https://github.com/kristianmandrup/geo_vectors which builds on _geo calc_ and provides various vector operations on geo points. 
-I also have plans to include _geo calc_ in "mongoid geo":https://github.com/kristianmandrup/mongoid_geo, the geo extension library for _Mongoid 2_. 
+The geo calculation API only requires that the point objects used, have a #lat and #lon method, which return the latitude and longitude respectively.
+The lat/lng should each be a Numeric (ie. Float or Fixnum) within respective 'geo ranges': (-90 to 90, -180 to 180).

-First define the points on the globe you want to work with.
-The GeoPoint initializer is very flexible with regards to the arguments it can handle.
